Win7 dhcp client: sending options

I am trying to change dhcp option 60 and 43 on my Windows 7 Cleint PC.
The standard option 60 - vendor class identifier is set to "MSFT 5.0" and I would like to change it to a different value of "Siemens". Similarly I want to send a Vendor Specific ID using option 43.
I have tried to add:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP\Parameters\Options\DhcpSendOptions
"60"=hex:3c,07,53,69,65,6d,65,6e,73
but try as I will, it will not send anything modified in the DHCP client request to the server.
Do I need to put the registry entry somewhere else or in a different format?
Thanks.

Hi,
After research, I found this registry key was supported by Windows CE and may not be supported in Windows 7. Otherwise, I have not found any documents that mentioned this.

E4200 IPv6 Causes Win7 DHCP Client Crash

When I enable IPv6 on my E4200, the Windows 7 DHCP client crashes. It also seems to crash the audio service, the event logger and a few other windows services. Please let me know what extra information you need.
Thanks in advance.

Check the even viewer for details.
Generally, a crash of windows or windows services is a problem of windows. It must not crash. You may have to repair your windows installation or the network stack. Check a microsoft forum for instructions.

Removing DHCP Client identifier Option 61

Long story short after wasting a LOT of time i figured out that my ISP won't offer IP if there's Option 61 Client identifier included in my DHCP Discover. (i tried throwing my MAC in there but it didn't work) is there any way to remove it? Or filter it out?

Welcome to the forums. Just so you know, this is a peer-to-peer support forum. Verizon does not answer questions here.
Sometimes the Verizon moderators escalate issues to the support team, which is an extension of the Verizon folk you can reach by using the "contact us" link at the bottom of these pages. If that happens to your issue, be sure to follow the instructions the moderators post.
Unfortunately, I do not know of any methods to reach Verizon's network engineers. They keep them very well separated from customers. Verizon keeps their residential customer contact very focused on the public support channels.
It's possible some of the other users here may know details about your question, but I'm not one of them.
Good Luck.

Win7 dhcp client wierd arp cache issue

Hi all,
I have this pc when connected to my switch it suppose to grad a dhcp ip, but it wasn't able to and i can see the ip 169.x.x.x(APIPA). Its set to dhcp. I noticed on my switch whenever the pc is connected, my switch gets a arp for 1.1.1.1 aaaa.aaaa.aaaa(my
pc mac address). If i remove the pc cable connection from the switch, after a while the arp for 1.1.1.1 would time out. I use a work around by changing the mac address of my pc and it would then be able to get a dhcp ip and work fine. There is no static arp
set on my switch. Pls advise. Thks in adance.

Hi,
Might we consider to make use of network monitor to take a look at the traffics for the 1.1.1.1 address?

Unfortunately no joy ... nothing has changed.
Does anybody have a solution to this problem or is it just no fixable ?
Thanks,
Matt.

found a solution : install dhcp (for example with darwinport , i.e. sudo port install dhcp) and use the dhclient command with a specific /etc/dhclient.conf
send dhcp-client-identifier "Guile";
send vendor-class-identifier "msft";
send host-name "GuileMac";

Setting options in DHCP client ...

Hi everyone, ...
Im having problems connecting to my corporate intranet DHCP network and investigating I realize the DHCP server requires a fixed DHCP Option 60 (vendor-class-identifier) with the value "MSFT 5.0".
Please, How can I configure this option in my osx DHCP client?
Regards,
Raul.

So you Mac is supporting Windows 2000 or older Microsoft operating systems? That is what Microsoft DHCP Vendor and User Classes. The 10.6.x system shouldn't need and changing.

WEC7 DHCP Allocator not sending ACK for a DHCP client

Hi All,
I have a WEC7 device configured as DHCP Allocator.
My PC (windows 7) will get ip from DHCP allocator successfully.
WEC7 ip settings:
ip: 169.254.0.1
subnet: 255.255.0.0
DNS: 0.0.0.0
My PC Ip after got ip from WEC7 DHCP Allocator:
ip : 169.254.0.3
net mask: 255.255.0.0
DHCP server: 169.254.0.1
DNS server : 169.254.0.1
Default Gateway: 169.254.0.1
I have another device (Ethernet based energy Meter), I am getting below problem
-> Meter will send DHCP DISCOVER Command (Broadcast)
-> DHCP Allocator Sends DHCP OFFER command back (Broadcast)
-> Meter will send DHCP Request to DHCP Allocator (Broadcast)
Now meter expects DHCP ACK command but DHCP allocator not sending any command.
within ~3 sec Meter start sending DHCP DISCOVER Command. this will happen continuously.
some time DHCP server will send ACK, but by that time Meter start sending DHCP DISCOVER command.
I Tried testing this meter by connecting to my PC directly and running a simple DHCP Server on my PC, here Meter connected to sample server and got ip from server.
The DHCP Concept is working with WEC7DHCP Allocator to PC client, Meter to PC as server but not with WEC7 server and Meter.
I compared the packets, only the difference i can identify is PC client is configured with Host name and Meter not have nay host name.
Any idea on whats wrong with WEC7 and Meter combination?
Do you know any third party DHCP server?
Please suggest me,
rakesh

Hi All,
The problem is not yest solved.
As I mentioned in last post, only the difference between My PC and Meter is Meter don't have Device Name and we are not able to configure it.
Device Name is the real Problem? If yes how can i eliminate this dependency?
For Static ip allocation at HKEY_LOCAL_MACHINE\Comm\ConnectionSharing\Addresses\Address, aslo there is dependency on Device name, is it possible to map the ip to MAC instead of Device name?
One more thing I observer that, DHCP allocator will send response for DISCOVER or REQUEST after 3 seconds. As Meter will send next discover before getting ACK, please check below log.
But in PC the entire DHCP registration will finish within 1 sec, I am not understanding why DHCP Allocator delaying for responding
Any suggestions will be really appreciated. Please recommend any third party DHCP Server if any available (we are ready to purchase also)
Thanks in Advance
DHCP Allocator (WEC7) Ip: 169.254.0.1
ip allocated from WEC7 for my PC : 169.254.0.15
Meter ip : 0.0.0.0

DHCP client\server request validation?

Is there a way to have for example a client send a variable with it's BOOTP request that matches a DHCP server side variable to complete a trust relationship between client\server before handing out an address to the client?
Basically the client would have an option set say "wagon21" and the server would have to have that value present. Then any clients that do not have the "wagon21" in their request would not be given a DHCP address.

Hi,
According to your description, my understanding is that you want to implement the function: DHCP server assign IP address to specific DHCP-enabled client.
In general, a DHCP server is willing to assign IP address to all reachable DHCP enabled client that sends DHCPDISCOVER message. For Windows Server 2008 R2 and later version, DHCP Server can distribute DHCP leases based on MAC address by setting
Filters – Allow/Deny. Detailed introduction and configuration steps, you may reference:
https://technet.microsoft.com/en-us/library/dd759190.aspx
Note that:
1. If allow list is enabled, the DHCP server provides DHCP services only to clients whose MAC addresses are in the allow list
2. If deny list is enabled, the DHCP server denies DHCP services only to clients whose MAC addresses are in the deny list.
3. If both allow and deny lists enabled, the block list has precedence over the allow list. This means that the DHCP server provides DHCP services only to clients whose MAC addresses are in the allow list, provided that no corresponding matches are in the deny
list. If a MAC address has been denied, the address is always blocked even if the address is on the allow list.
Besides, you may configure DHCP user class, detailed information reference:

Get DHCP clients list connected to DHCP allocator on WEC7

Hi All,
I Configured WEC7 Device as DHCP Allocator and is working fine.
I am able to see the connected DHCP clients information in Registry under ConnectionSharing/Addresses.
But for my application development I don't want to read the registry all the time to get updates of connected clients.
Are there any other options (API) available to read connected clients info (IP, MAC, Client Name etc).
And if i can register to some services for client connection status change notifications would be better.
Do you suggest any better ways to get clients info other than reading registry?
Thanks in Advance.
rakesh

Thanks Bruce,
Yes I can use your recommendation for getting clients list.
Do you recommend any third party DHCP server apps for WEC7 as I am getting some problems with DHCP allocator.
as mentioned here:
1. https://social.msdn.microsoft.com/Forums/en-US/a1b7eaae-48c6-4704-ae3a-d48db5cdb7b6/wec7-dhcp-allocator-not-sending-ack-for-a-dhcp-client?forum=winembplatdev.
2. also DHCP allocator will stops once it finds a real DHCP Server on the network as per MS documents.

I want to reserve a static IP address on my Airport extreme. What is the difference between reserving by MAC Address and DHCP Client ID?

I want to understand the differences in the way you can reserve a static address for a device on the network. I had previously set the device itself to an address and then reserved it with DHCP Client ID, which I thought was just the devices static addresss. I'm not sure if this was in fact correct or just happend to work. I know what a MAC address is, but I'm not really sure what the DHCP Client ID is. So it would be great if someone could clarify it, and the difference between reserving address by MAC Address or DHCP Client ID.

A MAC address is a unique identification consisting of letters and numbers in a form that looks like this:
xx:xx:xx:xx:xx:xx
Every network device has a MAC address, which can be found on a label on the bottom or back of the device. Apple calls this the Ethernet ID.
A DHCP Client ID is an optional name that you can assign to a device. For example, on your Mac....
Open System Preferences (gear icon on the dock)
Open Network
Click on Ethernet
Click Advanced at the lower right
You may be able to edit the DHCP Client ID here....for example.....you could enter MJ500's MacBook in the space provided. That would be the Client ID of your Mac.

Cisco ASA 5505 and DHCP Client Problems

Hi, i have a problem. I've connected my ASA appliance to an ADSL modem, and i dont get an DHCP address on the outside interface (e0/0). I use the asa-722-19.bin firmware.
I turned on the debugging for the DHCP client and could see that the ASA device was sending out broadcasts but a reply never came. Instead I connected the device to my internal network where the ASA got an address instantly.
I read somewhere that if I was to use ?ip address dhcp client-id fastethernet 0″, then I got an address from the ISP.
I tried looking for a similar command on the ASA5505 but I couldn?t find anything. I did however find a page on the Cisco site confirming my suspicions. It said some ISP?s require the client-id field of the DHCPDISCOVER request to be filled.
I've also read that this issue has beed fixed since a few weeks, now they have released version 7.2(2).22 where you can define ?dhcp-client client-id interface outside? in global configuration mode. Im running 7.2(2).19 and i cannot find any command like that in my appaiance. How do i fix my problem ? Or how do i get about recieving the 7.2(2).22 firmware update.
Regards !
Leif

Hi again! I thought I should share the solution that worked for me. I use software version 7.2(2) on this device. ASDM 5.2(2). In ASDM open configuration / Interfaces. Click in outside (my case 0/0) and press Edit. Then open the tab Advanced and set the correct Active Mac address. Fore some reason its empty by default and the ISP/modem don't like that. You will find the correct MAC address under the help menu / "About ASA". Im sure there is some another way to do this but this is a simple "how-to" that works with Swedens biggest ISP and their standard DSL modem.
When I used a Linksys DSL modem in bridge mode without the MAC address set I got an inside IP adress (192.168.x.x) from the modem to the ASA. After setting the MAC address I just had to do a renew and got the outside address right away. /Bjorn
(future users searchwords: no ip from isp, ASA 5505 and cable modem).

How to setup default gateway in a DHCP client. The default gateway will be the Ip address of the server that has RRAS installed, hence routing cabalities.

How to setup default gateway in a DHCP client. The default gateway will be the Ip address of the server that has RRAS installed, hence routing cabalities.

Hi Bill,
Thank you for replying back...Yes, I was actually asking how do you set the default gateway address on the DHCP server?,
I believe I got the answer below:
To configure the DHCP default gateway option Click Start, point to Administrative Tools and then click DHCP. In the console tree, expand the applicable DHCP server, expand IPv4, and then right-click Scope Options Click Configure Options, check 003
Router, type the applicable Server name and IP address, and then click OK.
Thank you

How-to: Check DHCP clients on the LAN ports??

Hi,
I can manage the DHCP clients on the wifi. But not on the LAN.
Can anyone let me know where in the AirPort Utility?
regards,

I have more info on this topic as I'm an interested party and would LOVE to see this work right one day....
The clients pop-up window does show physically connected clients and wireless clients, as well as clients physically connected to wireless bridges (check). Most of them. I have two wireless bridges with manually assigned ips outside the DHCP range and no port filtering. Only one of them shows up in this list, and I'm not sure why it does (not DHCP but has a reservation). Also - my linux host shows up, but the VM running inside it does not. Perhaps the virtual bridged adapter is confusing somebody up in the sealed time capsule but they get unique ip addys and are all accessible so the server must be seeing unique MACs (not to be confused with Macs)
I think it was a good try to provide a client view, its just buggy and feature weak.
I'm actually considering scrapping the airport as a router altogether - it doesn't even do local dns if you happen to have alot of clients on your home network, nor does it really support a separate local dns server because you cant tell DHCP what to send your clients. They decide for you so you dont fall down and bump your knee. Meh. And please - dont recommend I use Bonjour to Resolve Names on a Network...we run more than OSX here the whole world uses DNS and we should be able to too..

Macs show up as "unknown" on my router's DHCP Client Table

Both of my Macs, an Intel Mac Mini running Snow Leopard and a G4 iMac running Tiger show up as "unknown" in my router's DHCP client table.
All of my Windows PCs all show up with their computer names.
Is there a way to get my Macs' computer names to show up in the DHCP client table? The router is a Linksys RTP300.

Open Network System Preferences, click on the service you are using to connect to the network (airport, ethernet, etc), click on Advanced and go to the TCP/IP tab. There is a field for DHCP client ID. This may pass a name to the router and it may use it. I don't know.
Another option is the WINS tab. You can set the Netbios name (other than the default) and workgroup (and any WINS servers, if you know their addresses).

PO to supplier using external send option email (to multiple addresses)

Hello All,
We have activated PO external send option for our client but they want that PO should be sent to more than one ID of the supplier and it seems that is not possible by maintaining multiple addresses in Vendor Master's Address view as system only picks one having indicator ticked, also system does not allow to tick it for more than one address. Please let me know if it is possible using standard function to send PO email to more than one address.
I need to know if there is any standard way of doing this w/o using any development or ABAP work.
Also has anybody tried using disctribution list SO15 if it is possible?
Please help we are at Go live.
Regards
Anjan
Edited by: Anjan Dubey on Aug 12, 2009 10:28 AM

Hi,
From my opinion, it's impossible of the standard function in SAP system, so:
Firstly you need to confirm with your buyers, whether they really require to send the information to multiple addresses, maybe they can send the information to one contact person on vendor side, then the contact person can forward the email to other relevant people;
If have to do it, you need to develope an ABAP background job to do it!
Hope you can solve the problem!
Good luck
