Switch to second network card

Hi
SBS 2011.
The dell server has two network cards and one is disabled. Now the active card seems to be causing issues. What are the steps to reliably switch to the second network card?
Thanks
Regards

KA780G second network card doesn't work

Hi everybody,
Today, I put an second network card on the KA780G board (it's for a round robin network), on a free PCI slot, and this card isn't recognised by Linux and Windows (in Windows XP, when the network card is connected, my graphical card works bad as well).
I tested this network card in another computer and it's working well, I try with another type of network card and it's not working.
I upgraded the BIOS with the latest release and reset the bios parameters but it doesn't work.
Do I need to put some specifics parameters in the BIOS ?
Someone as an idea ?
Thanks
Matt

As you want... but I know the truth
Transfert a file takes me twice the time when the second network card was unpluged (the test was made with two differents files with the same size, this is for keeping disk caching speeding the transfert).
I think, your're not understanding, so let me explain the achitecture of my network : two computers pluged to my "super magic switch" (each with one network card) and my NAS with two round robin's network card.
I transfert one file from the NAS to the first computer and at the same time another file from the NAS to the second computer. The network speed was (on the NAS) about 24MB/s (see with the system monitor).
If you're right explain me why many people using port trunking with their switches ?

Installing a second Network Card

Having just installed Solaris 8 on an Intel based machine, the system is identifying two installed network cards.
Can anyone tell me how to configure the second Network Card - IP address etc as the Web Start package will only allow configuration of the first network card

You just need to create a new text file /etc/hostname.{nic-interface-name}
Lets assume the system has two intel etherexpress pro NICs installed. The intel NIC's driver
name / interface name is "iprb". So the two NICs are named "iprb0" and "iprb1".
The file /etc/hostname.iprb0 should already exist (created by the inital installation).
Just create /etc/hostname.iprb1 and put into this file the ip-address of the iprb1 interface.
You can also use a hostname in that file and add a hostname -> ip address mapping
into the /etc/hosts file.
During the next reboot the system will automatically bring up both the iprb0 and iprb1
interface.

Problems with SRW224G4 switch and Bridged Network Cards

Hello,
We have recently installed a SRW224G4 switch and have discovered that when we plug our DELL PowerEdge 2900 server into the switch, the switch loses all network connectivity and all of the LED's on the switch start flashing.
The server works perfectly well plugged into another switch, but as soon as we introduce the SRW224G4 into the network, either with the server plugged into that switch or any other, the problem re-occurs.
The only way we found we could eliminate this issue was if we disabled the Bridged Network connection on the two network cards on the server. If we do that, everything is fine, except the network performance of the server has dropped significantly.
The server is plugged into the 1GB ports on the switch, although we tried it on the 100MB ports and received the same problems. The switch reports that the ports are running at full-duplex.
Has anyone noticed this behavior before, and more importantly been able to rectify it.
Thanks in advance for your assistance,
Paul

I had this problem as well with any Linksys 2024 or rackmountable switch.. The trick is, you need to use the network cards management software to "team" or bridged the 2 NIC's otherwise the switch detects a loop and the whole thing locks up. So lame... Windows built in bridge mode stinks dont use it. When you use the Intel management software or Dell or HP's NIc management software you have the option to actually choose "redundant mode" where you can pick a Nic to be the primary, or you can choose Load Balancing where you can essentially double your throughput by joining the 2 nics.
In Windows 2008 Server, you actually do this by going to the Properties on the NIC in Device Manger. the software controls are now built right into the driver. pretty neat. 2003 you can check Device Manager the same way but not sure if it's the same as 2008, you might need to run the actual NIC management app.
Hope this helps

How to specify 2nd network card to TCP open and write?

TCP-Open does not have an option to choose which network card to use. It only has an open to connection but not an open from connection to enter. Is there anyway to select the second network card instead of letting the computer to choose?

pwrdesoto wrote:
Only the TCP-Listen allows the user to choose which network adapter to listen. The TCP-Open is require to open an connection to write to and it only has an input on where to connect to but not which network adapter to connect from.
tst is completely right. If you have two network cards they usually have different subnets that should not overlap. If the desired target adress belongs to one of those subnets the TCP/IP routing will automatically select the correct network card to bind the connection to. If you use an address outside of those subnets the default gateway will be selected.
And according to a Microsoft knowledgebase article it is a very bad idea to have more than one default gateway defined in the entire setup. If you do that the default gateway of the default (primary adapter) should be selected automatically but the routing can get really weird sometimes.
If this is not enough for your routing requirements you will have to manipulate the routing tables manually (and no it is no pretty business to do so). Look at http://support.microsoft.com/kb/140859 for a starting point about routing table manipulations under Windows NT (still applicable to XP) based systems.

Older G5 & new network card

I have a older G5 with what I think is PCI X and I need to install a second network card. I have 2 cards form a PC one is intel and the other a 3com. If i was to try these could it damage the g5?

Well I tried it and it worked fine

Network card name switching.

Hello. I have a problem with NICs switching names. I followed Wiki and added 10-network.rules in /etc/udev/rules.d but it seems there is no effect.
/etc/udev/rules.d/10-network.rules
SUBSYSTEM=="net", ATTR{address}=="11:11:11:11:11:11", name="eth0"
SUBSYSTEM=="net", ATTR{address}=="00:11:11:11:11:11", name="eth1"
SUBSYSTEM=="net", ATTR{address}=="00:00:11:11:11:11", name="eth2"
MAC addresses have been hidden but the one in my config are correct.
I have 1 NIC onboard (eth0) and one network card with dual port (eth1,eth2).
Also what is the difference beteen ATTR{address} and ATTRS{address}?
Wiki mentions something about:
With a recent version of udev, this problem should be solved automatically thanks to the /usr/lib/udev/write_net_rules program which runs the 75-persistent-net-generator.rules script which produces a 70-persistent-net.rules.
I can't find any of those files.

Assignment of network cards switches each boot (bizarre).

I'm working from a dell inspiron laptop which has both an ethernet port and a wifi card, which are registered as eth0 and eth1. I have no problems configuring rc.conf and related etcs to get the wireless card to work (no driver problems or anything), but they switch names each boot. Has anyone had this problem/ know why it would happen? I can confirm that all I need to do in order to get network running is switch all references of eth0 to eth1 (or eth1 to eth0) and /etc/rc.d/network restart in order to get online (as I am right now).

Network card: e1000g (Intel PRO/1000 MT) did not working properly

Hi to everyone!
I'm having some strange trouble.
All computers attached to one DLink gigabit switch
Server #1:
nf4-based motherboard, Intel PRO/1000 MT net card, onboard net card (forcedeth driver used) Ubuntu Linux 2.6.25 kernel version.
All just working.
Server #2:
nf6-based motherboard, same Intel net card, SunOS 5.11 snv_86.
All just working.
Server #3:
Same as server's #1 nf4-based motherboard. Same onboard card. Same SunOS 5.11 snv_86 as server #2 have installed.
Its work. BUT..
Intel card is not working as expected.
It is seen by system. It is properly up and running. It is sending packent and receiving packets. Ierrs=Oerrs=Collis=Queue=0.
But thru e1000g0 interface no one computer can reach this one, and from server #3 no one computer is seen thru e1000g0. Exept...
Except two old Sunray1 devices (attached to the same switch for testing purposes)! But even these devices seen only by arp requests, and is not pingable.
It is some mistery, but if I turn on jubmo frames, these rays got a picture from SRSS, testing on this sevrer! Not for long, heh, they hung up fast, but this is proof a physical connection :)
So, I can not disable onboard network card on Server #3 - server becoming unreachable :(
I know, those network cards must work on Solaris - as they did it on server #2. I know, those network cards work with my nf4-based motherboards - as they did it on server #1.
But I can't uderstand, whait is going on with e1000g driver on server #3!
P.S. Kernel driver e1000g settings are the same. All difference from servers #2 and #3 is: #2 had Intel netcard installed then Solaris was setting up, and #3 had Intel netcard installed later. All netcards are working (I trying to swap them from one computer to another - did not change anything).

*) #3 thinks it is sending, but a NIC/driver error prevents it.NIC is fully health. It is tested on another PC. Driver error - or driver's bad implementation - is the one I'm thinking.
*) #3 has a bad transmit pair of wires (would affect all communication)This patchcord works w/o problems on other PCs and even on onboard NIC of server #3.
*) Network problemsHeh :)
*) Firewall or other device is dropping the ARP repliesIt is some very stealthy and very selective firewall, affecting only external NICs :)
BTW, then cord is attached to NIC, it sends "who has this IP" requests, asking to be shure there will not be an IP conflict. No one seen this requests.
*) #1 has a NIC/driver error preventing it from seeing the reply.Only for send from #3? It is like a firewall on #3 :) And, there is more PCs, not only #1-#3. No one can see #3's replays (or asks), not only #1..
I'm repeating: this PC works in network now on onboard NIC w/o problems. But onboard NIC is only 100 Mb/s, and we need 1 Gb/s.
I was thinking, Solaris took wrong MAC for NICs - but not, ifconfig shows the same MACs as marked on NICs.
Even more, yesterday i plumbed e1000g1 - second Intel NIC in server #3. And I was surprised - it worked perfectly!
But I make "touch /reconfigure; init 6" - and after reboot, no one of two Intel NICs working again :( They both have the same behavior - no one can see packets they sends.)
I even try to restrict connection on 100 Mb/s by driver's .conf modify - it works, link become yellow instead of green (take a note, NIC is able to "speak" properly with switch!), but all other stay the same.
Strange, really strange behavior. More strange is a fact this NICs work on another instance of same SunOS, but on different motherboard, while the same MB with same NIC is working w/o problems under Ubuntu. Looks like some bug in Solaris driver.

HP Management Pack - why would a rule be used for a network card error?

Hi,
I am asking this question with regard to the HP proliant management pack but my question is about the more general "rule" v "monitor" question which generally I understand (I think).
We get alerts for HP network card failures. This is rule based and basically looks for event "2" in the event logs. The same thing happens though if a cable gets pulled or a switch fails for a few seconds for instance.
The question I am getting asked by admins is to override this as its a "false alarm". I have pointed out people shouldnt just pull a network cable (maintenance mode please!) and if switches are failing then use the SCOM alert to let the network
team know... Plus if the card genuinly does fail this is the alert. BUT they are asking why isnt this a monitor anyway? If the network card is OK I think event 4 gets logged. So why didnt HP write it as a monitor that would close when it sees the success event?
My main thinking was if they had you wouldnt get to know about intermitant faults that dont last long. For instance the card would be down for 30 seconds but the monitor would close as soon as it was back up and you wouldnt see it.
Any thoughts?
thanks

My guess is because they have tools that compete with MSFT and do not sell their MP's. So now they have to have one of their own FTE's creating a management pack for a competing product to monitor their hardware. If it worked better than HP Openview,
then maybe more people would switch to Openview and dump SCOM...
Honestly it comes down to resources, and the fact, similar to MSFT management packs, they are FREE, so how can you justify spending all the time and resources to create something and then give it away for free? You can't, so you speed through it, and
drop it to the public, let them find the issues, and stress test it, etc. (not a fact, just my honest opinion after working with this product for over 13 years). MSFT is guilty of this as well, they have had their fair share of problem management
packs...but they are FREE.

Instaling second ethernet card / sharing internet connection

Hiya.
Is it possible to share my cable broadband service ( PS3 etc ) through my PPC G4, maybe by installing a second ethernet pci card and sharing the internal ethernet, or is there any other possibilities. no airport, but do have a D-link bluetooth dongle...

As other posters have pointed out, you don't need a second ethernet card to share out your connection - if you have an existing router (with a number of ethernet connections), you can connect your game consoles to that, and your ISP will be none the wiser. Your ISP will still give you one IP address; your router does the translation into multiple private IP addresses (eg 10.0.1.1, 10.0.1.2, etc)
Another option is to buy an inexpensive network switch, put that between the router and the Mac, connect the other devices to the switch, and turn on sharing from ethernet to ethernet. But you really don't need to with a router on the network.
If you share out your Mac's internet connection, the devices behind the connection will get IP addresses in the range 192.168.2.x (the Mac will effectively be their router/DHCP server at 192.168.2.1).

HP Elitebook 820 G1 - Network card issues

Notebook model : Elitebook 820 G1 OS : Win 7 Pro, 64bit Network card : Intel i218-LM Problem: A user in my organisation with an 820 G1 is experiencing laggy and intermittent network connectivity. There is a noticeable (but infrequent) latency when opening some webpages - both external, and also internal intranet pages which normally open instantly. There can be a delay of 10 seconds or more. This also happens when browsing to network folders, fileshares, etc. Any type of network activity basically. Pings return intermittent results. There are 200 other users on this particular network and they aren't experiencing any issues at all. Most of our switches were changed out last year for new ones. We have ruled out or changed the following, with no effect : DNS / Cabling / Switches / authentication issues / driver / Power settings / wake on lan / etc. All possible factors beyond the network card itself have been isolated and discounted. The same issue does not occur when using our internal Wifi instead of cabled LAN. Which, ironically, is usually the reverse. As a last resort, we compeletely removed the HDD in the laptop, replaced it with an SSD and rebuilt it with a fresh install of Windows 7, along with the very latest HP drivers. The issue still persists, so at this stage I'm convinced it's a hardware problem. However, network connectivity does work most of the time and the issue is sporadic so it's difficult to replicate it when trying to talk to HP support. Anyone else seen this with the Intel i218-LM cards?

Further to this
i had a similar issue and it was due to using an invalid fingerprint to try to unlock the drive via the win magic drive encryption
using the local admin password for the local admin account let me straight in

RE: Is there a way to have 2 network cards on the samemachine

Sean,
I mean I am always connecting to the nodemgr of the 2nd environment
successfully. Only when I run the client part of the application that I know
is up, I get a response from the Name Server that it is actually the first
IP address.
I checked again. I defenitely have FORTE_NS_ADDRESS set to IP:5004, in my
case, and not the hostname. I don't have FORTE_LOCATIONS set any where. the
NS_ADDRESS for env2 has only 1 IP address associated with it. My Forte
Control Panel on the client, and hence the NS address has only one entry.
I tried going into escript like you said, and the name service still thinks
it is IP1.

Subject: RE: Is there a way to have 2 network cards on the same

Hmmmm? That is a little odd! Let me rehash what I think you are saying.
You now have two environments each with their own name service with
FORTE_NS_ADDRESS set to a different IP:Port combination. For example you
are doing the steps:
FORTE_NS_ADDRESS=255.255.255.1:5000
start the nodemgr for env 1
FORTE_NS_ADDRESS=255.255.255.2:5000
start the nodemgr for env 2
Now when you start a client you are always getting the address for env 1
back from the nodemgr. I assume you actually mean the name service? Or, do
you mean you are always connecting to the nodemgr & name service for env
1?
If the first scenario is the case and you are connecting to the nodemgr
for
env 2 but getting back IP's for services listening on the card for env 1 I
would ask you what you are setting the FORTE_LOCATIONS value to before you
start each service. If you are not setting it or are using the host name
it
will register using the IP for the primary network card associated with
the
machine name and I am again assuming that this is env 1. You need to set
the FORTE_LOCATIONS variable to 255.255.255.2:0 (based on the steps above)
before starting your services.
If the second scenario is the case I would have you check what the
FORTE_NS_ADDRESS is set to before you start up the client. Once again it
must be the IP:Port combination not host:port combination if you want to
get
anything other than the primary card.
I would also suggest that you do the following. After everything is up
and
running execute the following commands:
escript -fns "ip for env1":port
findsub nameservice
showpart
What you should see is everything currently registered under the name
service. It will have the name and any "locations" (IP and port) that it
is
registered as listening on. I would look for the nodemgr and see where it
has advertised itself. I would then look for any services you expect to
be
registered there and also verify where the have advertised themselves. If
there are multiple locations listed for any one service, the client will
use
the first one in the list.
Do the same for env 2.

Hello Venkat,
I probably should have mentioned this before. Your are correct. Forteis
doing a host lookup if you are providing a name for examplemachine1:5000.
You can bypass the host lookup by using the actual ip dot addressinstead
for example 255.255.255.255:5000. This way you are taking the name
service
out od the picture and Forte will use the address provided.

Subject: RE: Is there a way to have 2 network cards on the same machine
My requirement is that my second card serves as best case performance
testing piece. This eliminates the network completely. We went one step
ahead and created a new enviromnent for the second card. Whatever I do,
the
nodemgr is returning back the IP address of the first card, even thoughmy
FORTE_NS_ADDRESS does not have the first card in the picture any where.
I think Forte is doing a host look up and returning the first IP address
it
finds, as opposed to returning the IP address specified in theenvironment
variable FORTE_NS_ADDRESS. Is there a way to trick it?

Subject: RE: Is there a way to have 2 network cards on the same

OK, you ran into one of the issues. That is, if both addresses areknown
to
the client that is trying to contact the partition it will always usethe
first address in FORTE_LOCATIONS. This is because FORTE_LOCATIONS was
designed more as a failover mechanism. So it will always try the
first
address in the list and if it succeeds, there is no reason to move onto
the
second.
Now, the second issue is that there is currently a problem with theclient
failover to the secondary address in FORTE_LOCATIONS. If the firstentry
fails it is supposed to retry on the second entry. Instead, it
retries
the
first entry again. I know that Forte knows about this but I do nothave
a
bug number on it.
With that said, lets look at a possible solution for you. If the real
objective here is to have a back up network card available for fail
over
on
the same machine, or use one card to advertise outside your firewalland
one
to use inside, then you will have to contact Forte to determine whenthe
failover problem will be fixed. But, if the objective is to loadbalance
across the network cards you could have the environment manager listenon
both ports and then alternate your server partitions across both
cards.
For
example:
set FORTE_NS_ADDRESS=card1:5000;card2:5000 and then start up the
environment
manager
set FORTE_LOCATIONS=card1:0 (the 0 in the port causes the OS to pick a
port)
and start partition one
set FORTE_LOCATIONS=card2:0 and start partition two
and so on....
In this scenario the environment manager will be listening on bothcards
but
each server will be listening on only one of the two cards. So if a
request
comes in for partition1 it will go through card one and if it is for
partition two it will go through card two. You could assign your
partitions
to cards based on expected load.
Well, I am done. I hope this helps!

Sean,
Thanks for your reply. I tried the approach. I was not very specificin
my
question. I do need the ability for server applications to listen and
server
on both the network cards.
I was succesfully able to make the nodemgr listen on both the cardsand
actually serve requests coming in from both the cards. But, followingyour
advise, I took a cautious step with FORTE_LOCATIONS. Here is what I
noticed.
I have an application that has 6 partitions in total. I used
FORTE_LOCATION
to make it listen on 1. Both the cards. 2. Swapped the IP addresses
for
both
cards for this application. 3. One card that I want it to listen on. I
tried
all approaches by exporting the locations variable for just this
application. The nodemgr recieves a request from this pc connected onthe
second card to talk to one of the partitions. The node mgr responds
with
a
proxy - with the ip address and socket number of the first card. The
FORTE_NS_ADDRESS variable looks like this:
IP1:5002;IP2:5002.
Is it possible atall to resolve my problem, without having a seperate
environment?
Thanks

Venkat,
Actually, it is possible for Forte to listen on more than one IP andport
combination. The first reply to your message was correct. If you
set
the
FORTE_NS_ADDRESS to contain multiple entries before starting the
name
service, it will advertise on both. For Forte servers you use the
FORTE_LOCATIONS env variable to get it to advertise on multipleip:port
combinations.
We were doing something very similar with another customer I was at
to
get
around a firewall. I will warn you that there are some issues with
FORTE_LOCATIONS that may keep that portion from working. However,
from
reading your note, it appears that all you need is for the nameservice
to
advertise and listen on multiple ports and that works fine. I justtested
it again for sanity sake and it worked. I ran my test on NT using
Forte
3G2.

Venkat,
Technically yes this is possible, though not in Forte. A nameserver
can
only listen on one port.
To implement this scheme you will have to write a proxy service (insome
language
including perhaps forte) which listens on the well-known port on the
second card, reads requests, then forwards them to the realnameservice
(wkp on the first card), and forwards replies back. This is not
trivial, but some firewall toolkit vendors supply stub code to write
application specific proxies.

Hello Venkat,
I probably should have mentioned this before. Your are correct. Forte is
doing a host lookup if you are providing a name for example machine1:5000.
You can bypass the host lookup by using the actual ip dot address instead
for example 255.255.255.255:5000. This way you are taking the name service
out od the picture and Forte will use the address provided.

Subject: RE: Is there a way to have 2 network cards on the same machine
My requirement is that my second card serves as best case performance
testing piece. This eliminates the network completely. We went one step
ahead and created a new enviromnent for the second card. Whatever I do, the
nodemgr is returning back the IP address of the first card, even though my
FORTE_NS_ADDRESS does not have the first card in the picture any where.
I think Forte is doing a host look up and returning the first IP address it
finds, as opposed to returning the IP address specified in the environment
variable FORTE_NS_ADDRESS. Is there a way to trick it?

OK, you ran into one of the issues. That is, if both addresses are known
to
the client that is trying to contact the partition it will always use the
first address in FORTE_LOCATIONS. This is because FORTE_LOCATIONS was
designed more as a failover mechanism. So it will always try the first
address in the list and if it succeeds, there is no reason to move on to
the
second.
Now, the second issue is that there is currently a problem with the client
failover to the secondary address in FORTE_LOCATIONS. If the first entry
fails it is supposed to retry on the second entry. Instead, it retries
the
first entry again. I know that Forte knows about this but I do not have a
bug number on it.
With that said, lets look at a possible solution for you. If the real
objective here is to have a back up network card available for fail over
on
the same machine, or use one card to advertise outside your firewall and
one
to use inside, then you will have to contact Forte to determine when the
failover problem will be fixed. But, if the objective is to load balance
across the network cards you could have the environment manager listen on
both ports and then alternate your server partitions across both cards.
For
example:
set FORTE_NS_ADDRESS=card1:5000;card2:5000 and then start up the
environment
manager
set FORTE_LOCATIONS=card1:0 (the 0 in the port causes the OS to pick a
port)
and start partition one
set FORTE_LOCATIONS=card2:0 and start partition two
and so on....
In this scenario the environment manager will be listening on both cards
but
each server will be listening on only one of the two cards. So if a
request
comes in for partition1 it will go through card one and if it is for
partition two it will go through card two. You could assign your
partitions
to cards based on expected load.
Well, I am done. I hope this helps!

Sean,
Thanks for your reply. I tried the approach. I was not very specific in
my
question. I do need the ability for server applications to listen and
server
on both the network cards.
I was succesfully able to make the nodemgr listen on both the cards and
actually serve requests coming in from both the cards. But, following your
advise, I took a cautious step with FORTE_LOCATIONS. Here is what I
noticed.
I have an application that has 6 partitions in total. I used
FORTE_LOCATION
to make it listen on 1. Both the cards. 2. Swapped the IP addresses for
both
cards for this application. 3. One card that I want it to listen on. I
tried
all approaches by exporting the locations variable for just this
application. The nodemgr recieves a request from this pc connected on the
second card to talk to one of the partitions. The node mgr responds with a
proxy - with the ip address and socket number of the first card. The
FORTE_NS_ADDRESS variable looks like this:
IP1:5002;IP2:5002.
Is it possible atall to resolve my problem, without having a seperate
environment?
Thanks

Venkat,
Actually, it is possible for Forte to listen on more than one IP andport
combination. The first reply to your message was correct. If you setthe
FORTE_NS_ADDRESS to contain multiple entries before starting the name
service, it will advertise on both. For Forte servers you use the
FORTE_LOCATIONS env variable to get it to advertise on multiple ip:port
combinations.
We were doing something very similar with another customer I was at toget
around a firewall. I will warn you that there are some issues with
FORTE_LOCATIONS that may keep that portion from working. However, from
reading your note, it appears that all you need is for the name serviceto
advertise and listen on multiple ports and that works fine. I justtested
it again for sanity sake and it worked. I ran my test on NT using Forte
3G2.

Venkat,
Technically yes this is possible, though not in Forte. A name server
can
only listen on one port.
To implement this scheme you will have to write a proxy service (in some
language
including perhaps forte) which listens on the well-known port on the
second card, reads requests, then forwards them to the real nameservice
(wkp on the first card), and forwards replies back. This is not
trivial, but some firewall toolkit vendors supply stub code to write
application specific proxies.

Is there a way to have 2 network cards on the samemachine

Hmmmm? That is a little odd! Let me rehash what I think you are saying.
You now have two environments each with their own name service with
FORTE_NS_ADDRESS set to a different IP:Port combination. For example you
are doing the steps:
FORTE_NS_ADDRESS=255.255.255.1:5000
start the nodemgr for env 1
FORTE_NS_ADDRESS=255.255.255.2:5000
start the nodemgr for env 2
Now when you start a client you are always getting the address for env 1
back from the nodemgr. I assume you actually mean the name service? Or, do
you mean you are always connecting to the nodemgr & name service for env 1?
If the first scenario is the case and you are connecting to the nodemgr for
env 2 but getting back IP's for services listening on the card for env 1 I
would ask you what you are setting the FORTE_LOCATIONS value to before you
start each service. If you are not setting it or are using the host name it
will register using the IP for the primary network card associated with the
machine name and I am again assuming that this is env 1. You need to set
the FORTE_LOCATIONS variable to 255.255.255.2:0 (based on the steps above)
before starting your services.
If the second scenario is the case I would have you check what the
FORTE_NS_ADDRESS is set to before you start up the client. Once again it
must be the IP:Port combination not host:port combination if you want to get
anything other than the primary card.
I would also suggest that you do the following. After everything is up and
running execute the following commands:
escript -fns "ip for env1":port
findsub nameservice
showpart
What you should see is everything currently registered under the name
service. It will have the name and any "locations" (IP and port) that it is
registered as listening on. I would look for the nodemgr and see where it
has advertised itself. I would then look for any services you expect to be
registered there and also verify where the have advertised themselves. If
there are multiple locations listed for any one service, the client will use
the first one in the list.
Do the same for env 2.

T520 won't detect Network card in WDS/WinPE/Ghost image disk

Hello all,
I figured I would just post this so I could save 2 days of someone elses life.
I'm not sure how many other modes have the EFI and UEFI bios's in them but this has caused a lot of problems when trying to capture an image / image the Lenovo T520. So for anyone else that is having these problems here is how I got around the problem.
The Problem:
While trying to boot up off a Capture image with a CD or PXE boot for our WDS server the laptop would not detect the network card giving no IP address and listing the adapter as a hybrid. When trying to do a ipconfig /renew it would give an error around the lines of the loopback something or other ....... the adapter could not be contacted or initated.
I instantly thought this was due to the vanila WinPE / Capture image not having the drivers for the Lenovoo T520, so I went to the website downloaded the new drivers and injected them into the WinPE disk(You will want ot use the NDIS Drivers which are included in the package for this). Following this process it would still not detect or install the NIC. After many hours of searching it would apear this was due to the EFI/UEFI bios options not going through the proper boot cycle when in a PE enviroment. The solution was to mess around with the EFI/UEFI switches in the WinPE boot image during the creation proccess as listed below:
ocdimg -m -o -u2 -udfver102 -bootdata:2#p0,e,bc:\winpe_x64\etfsboot.com#pEF,e,bc:\winpe_x64\efisys.bin c:\winpe_x64\ISO c:\winpe_x64\winpeuefi.iso
The link with more details is here: http://support.microsoft.com/kb/947024
Eseentially once the new boot image was complied with the proper EFI / UEFI options enabled it went through the proper boot process detected the NIC and installed the drivers which I previously provided on the disk and we where off to the races imaging the new laptop.
Hopefull this will help some others who are struggling with this or any other model that has this type of bios.
Cheers, and thanks
Please feel free to post any additional comments to help others if you found better ways to get around this
One side note the EFI/UEFI to legacy mode only does nothing for the NIC problem, I have seen some posts where they can help with the hard drive issues when imaging, however as for the nic not loading in PE enviroments this setting in the BIOS did not reslove the problem.

Hi Rusty1234
If I did not remember wrongly, you may present or add drivers (network, hardware) under WDS / Ghost software or copy necessary drivers (e.g. your T520 network card drivers) under it's PXE / boot section.
Happy 2012!
