DHCP not delivering IP addresses

I had DHCP enable and everything working great. After a manual reboot of the system, DHCP is not delivering IP address to the clients.
If I insert the values manually, everything works.
Any ideas?

Ater restarting everything works... :s

WRVS4400N : DHCP not assigning IP addresses if WAN link is down

Hello,
With the latest firmware installed (the one suporting fixed IP based on MAC), I have one problem: the DHCP server is not assigning addresses when the WAN link is down. When it is up, it generally assign IP based on the configuration binding (MAC/IP). But it sometimes fail to do so. Before using the wrvs4400n I had no issues with DHCP wrt54G and other routers.
Any hints ?
Thanks.
V.

Hi there!
Thanks for contacting the business support - other guys got the same problem.
I'm now back on firmware version 1.00.16 and everything works fine.
But the new features were nice to have!

Group mail not delivered - "Recipient address rejected: Access denied"

Apparently I'm not alone who is having the issue with mails being rejected while the addresses are fully valid.
Specifically, I have a mail distribution group created, with several e-mail addresses configured. The group is properly set to accept mails from the outside of the company.
The emails sent from the company accounts are delivered properly. However, when an email is sent from the outside, it gets "Recipient address rejected: Access denied" error message back. There is no trace of such an email in "message trace".
What helps (others on the forum as well as me) is switching the Domain type in Mail flow / Accepted domains from Authoritative to Internal relay. The emails start to be delivered.
The main reason why I do not want to have ths setup is that when an invalid email address is used, the email apparently keeps going in rounds between servers until the maximum number of hops is reached and then the message that is sent back to the sender
is just that - "554 5.4.6 Too many hops".
Is there any intention to tackle this problem?

Hi,
The first thing that comes to my mind is the 'Require that all senders are authenticated' setting. Is that setting to found your distribution list? If, try uncheck that.

DHCP not handing out addresses

Hi all

As a test, if you run it without any third party services running, does it do the same thing? To do that, from a Start/Run box, run
msconfig, select Service tab, click on Hide Microsoft Services, then make sure the list left is checked, and disable them, and restart. Run it as a test, and if it doesn't occur, then you know it's third party software doing it.

Dhcp not allocating addresses

My network is managed by Mac Mini Server (Lion) with an Airport Extreme.
I have the wireless set up as WPA2 Enterprise with the Radius Server, Open Directory, DNS and DHCP running on my Mac Mini Server.
In the past week, possibly since the last updates were applied, all wireless devices are having real issues connecting to the network. They are authenticating OK but an address is either never assigned or appears after 5 or ten minutes. To verify this I tried to connect iPad. This was set to use DHCP and the wifi symbol appears intermittently at the top of screen but on the networks page a spinning wheel appears next to the network name and the address details (i.e local address, router, DNS, etc.) are all empty. If I configure for manually entered address details the deveice connects immediately and works fine. Switching back to DHCP and the problem comes back (i.e. connects to wifi but no address is ever allocated).
Any ideas on why DHCP would suddenly stop working. I have tried restarting the service, rebooting the Airport, rebooting the server but nothing seams to fix it. Every thing was working just fine for the past 6 months.

Thanks for reply.
Router is:
Netopia ADSL Gateway 3346N-002
4 port 10/100 Ethernet built-in
The settings in the Control Panel didn't show anything of note.
What's interesting is that when the user's laptop went back to the hotel again today, the same issue cropped again -- hotel's DHCP not giving IP Address. The office DHCP server was assigning no problem.
Then... I checked Access Connections Profiles and noticed that "Disable this wireless radio when switching to a different location" was not checked for any profiles.
I checked off on all profile and then the hotel DHCP made the connection.
I did read somewhere that a possible fix is to do an IPCONFIG/RELEASE * and then do an immediate Shutdown/Restart. Issue is that I didn't have this option on the user's laptop before I made the Access Connections fix.
Please reply to clarify or add anything -- I appreciate your quick response because I spent 4 additional hours last night.

Cisco 891 not getting IP address with DHCP with latest IOS

Hi,
I have a few Cisco 891 routers that are configured as DHCP clients on the WAN interface.
For some reason when I boot the router with a late IOS, the router is not receiving an address.
It works just as expected with the older IOSes.
Any ideas of what changed?
This is how the interface is configured:
interface FastEthernet8
ip address dhcp
no ip redirects
no ip unreachables
no ip proxy-arp
duplex auto
speed auto
no cdp enable
This IOS does not work:
c890-universalk9-mz.154-3.M2.bin
While these do work:
c890-universalk9-mz.150-1.M7.bin
c890-universalk9-mz.151-2.T2.bin
c890-universalk9-mz.152-1.T1.bin
Doing a "show ip interface brief" shows that FastEthernet8 is unassigned with the affected IOS.
With the older IOSes there is an IP address.
I had to downgrade two routers due to this issue, and did not have plenty of time to troubleshoot.
Both of the routers are connected to DSL from the same ISP...
Anyone seen anything like this before?

Add another one to the list.
I have a MacBookPro3,1 that connects to WIFI no problem. It used to connect to ethernet when I originally bought it, however I've been using WIFI exclusively for the past 2 years.
Recently I had a need to connect via ethernet and it wouldn't work at home (apple airport router). I next tried connecting via ethernet at a friends house using a linksys WRT54G, no dice either. I have the computer in the lab today (University Network) and I get the same error. 3 different locations, 3 different routers, all same problem. It used to connect to home and university networks ethernet right away.
IP address assigned is 169.xxx.xxx.xxx - subnet - 255.255.0.0
no other info. It's showing up as connecting to the network, but unable to communicate with DHCP. It does work if I enter all of the information in manually.
At first I thought I had messed something up in networking preferences as I tend to play around with things alot. However I did a complete system format, and fresh install of OSX Lion and I still have the same problem, without any of my meddling around to confuse things.
What gives?

DHCP: Some clients not getting IP address

Recently setup a new DHCP server on Mac OS X Server 10.5.8 running on an Xserve. We migrated from a Linux server.
The Xserve was originally just a file server. So the only services currently running are: AFP, DHCP, NFS, and SMB. No additional software is running.
The DHCP server ran just fine for the first couple weeks. But then we found some computers just stopped getting IP addresses from the DHCP server. Some were new computers introduced to the network. Some were laptops that had left and come back. However, the DHCP server is definitely still giving out IP addresses and renewing them for most new and existing computers. There have been five computers that have not gotten IP addresses so far, and that had been the case both on the wireless and on a wired connection. Two were PC's, one running Windows 7 and one running Windows XP with Lenovo's ThinkVantage software. The other three were different models of MacBook Pros.
For those five computers, we managed to get them working in two ways. One, we can select to use DHCP with a manual address. When we do that, it manages to pick up all the other information from the DHCP server like DNS and gateway. The second thing we can do is configure the DHCP server to supply a static IP address by providing it with the MAC address of these machines. When we do that, the computers receive the IP address from the DHCP server.
So I guess you could say the problem I'm experiencing is for a few computers the DHCP server seems to only be able to provide static addresses, but not dynamic ones with a lease time.
I have logging set to the highest for the DHCP server. Below is the first thing I noticed that keeps showing up. Sometimes it shows a different MAC address than the one below. None of the afflicted computers have that MAC address, though. I have not seen any other errors in the logs for the DHCP server.

DHCP server does not assign IP addresses SG500 firmware 1.3.5

good day collegues
has any of you come across the following issue:
my switch (after upgrading to the newest firmware 1.3.5) does not assign IP addresses to some of the hosts.
after a couple of hours I managed (do not even how) to force my switch to assign IP addresses only to some of the hosts.
still some of them cannot get the IP address and remain with "funny" IP address like i.e. 169.254.100.100
additional info
1. if I boot my switch with the previous version of firmware (1.3.0.6) everything is OK. all my hosts get correct IP addresess
2. the hosts which do not get IP address were perviously entered in stat host table - now removed, ARP cleared, etc, everything many many times rebooted.
I ran out of ideas, could you pleae give me some hints ?

Hi Andbor, please make a backup config of your file, factory reset the switch.
After this, manually configure a DHCP scope without any other configuration.
Just something simple like this
ip dhcp pool network GUESTS
address low 10.10.14.1 high 10.10.14.254 255.255.255.0
lease infinite
netbios-node-type b-node
default-router 10.10.14.254
dns-server 10.10.10.1 62.233.233.233
Verify your machine receive IP address with no other configuration.
In some ways, I'm afraid some of your connections black listed due to the arp inspection.

DHCP and Pointers for Addresses Not Released

I was aksed to see if there could be anything to fix this:
Our DHCP hands out new IPs within a 24 hour period.
The Macs in our mixed environment ( 300 PCs, 52 Macs)
will get assigned an IP Address, and then keep it for the day, and in the morning release and get a new one at boot.
HOWEVER, according to the DHCP server, the IP address
still "points" to the Mac, and thus the DHCP server
thinks its in use.
Our IS department is convinced its a Mac problem,
and there has to be some way to make the Macs
release address, and tell the server its released
that address, so that the Server can re-assign
the address down the line.
I personally do not think so, I think it is something
on the DHCP server's end, but I'm not sure.
Any help on this or insight or general theorizing
would be helpful. I have also posted this over in
microsoft.public.windows.server.dns,
if this post seems familiar....

Backing up a bit - what is the actual problem leading
to this investigation? A DHCP server keeps a database
of pairings of IP addresses with MAC addresses (not
Macintosh addresses). It should automatically prevent
any MAC address from consuming more than one IP
address.
Most likely it is the fact that we have close to 400 total computers on site, and that we only have a limited available blocks
of IP addresses ( ranges 10.0.0.x, 10.0.1.x, and 10.0.2.x), and although at any given time not all 400 total computers
are on the network ( people out of house, some only go online
when necessary for updates etc), the fact that the DNS pointers keep saying that, for instance that an imac
on my desk is using 10.0.1.174, and that the DNS server is
saying that it should also be 10.0.1.146 ( which it had yesterday) as well as 10.0.1.174, but since the DNS server thinks
that 10.0.1.146 is still validily assigned, then it won't release this address, and thus on the PC side, they cannot
get the address 10.0.1.146, hich then causes a shortage of addresses.
I hope I explained that the best way possible; to me, it seems like it should be an easily fixed cache problem, if a cache exists for the DNS pointers, that it could be
regualrly dumped?

DHCP via Hyper-V VM, Server2012r2 Hyper-V host, clients not getting IP address

You have to authorize a dhcp server as Britv8 says. That's the only way it'll start dishing out leases. That's standard for Windows DHCP server in an AD Domain.
Also there's 0 reason to mention Hyper-V here. The whole point of virtualization is to do hardware level abstraction.

I recently encountered this. Setup:
Initial setup of the system was at a different location from its final destination, with different network equipment (switches) between the two. No teaming is involved, however.
Set up the system at its final destination, with DHCP via a Hyper-V VM (Server2012r2), Server2012r2 Hyper-V host, physical clients on the lan were not getting IP address.
The physical server box has a 4-port Intel Gigabit ethernet card.
I moved the setup (Hyper-V Virtual Switch manager) so that the interface for the DHCP server VM was isntead using one of two built-in Broadcom adapters.
While this topic seemed promising,
http://community.spiceworks.com/topic/251317-hyper-v-vm-not-leasing-ip-s-dhcp
unfortunately, "fiddling about" was not what I was looking for as possible solution.

Send Email not delivering emails to addresses other than yahoo

Hello,
I have an application that works well, built with ADDT with custom coupon payment gateway, verification and license download and the final step - sending email to customer after every successful transaction.
I have noticed that emails are not delivered to my business email account but whenever I change the email address to a yahoo email address and attempt a transaction the email gets delivered immediately.
The email address is pulled from a recordset from the current logged in user's personal information table.
Any idea why this is so? Is there a problem in ADDT as I would have believed that public email addresses like yahoo or gmail should be more difficult to deliver emails to as against fully functional non public email addresses.
I tried changing my password on this forum (Adobe forum) this morning and I got the forgotten password email sent to the same email address that may application has refused to deliver emails to so there is nothing wrong with the email address itself.
Any help would be greatly appreciated.

Hi Gunter,
Thanks for your response.
I have contacted the support team managing my dedicated server and they claimed they got an email (sent to their email address) while testing the application (www.ijann.com/onspeed/tell_a_friend.php).
I tried to send email to another email address (other than yahoo) on my dedicated server and it was delivered immediately.
So, it means emails are not only getting delivered to yahoo email accounts.
But my business email address (not on my dedicated server) never gets any email from the application.
I have just sent an email to the support team managing the shared server where the business email is residing.
I will post an update when this is resolved. As you implied, it may be with the setting on that email account which is showing "More Aggressive Action" towards emails tagged as SPAM. Maybe the next step is to see the criteria for tagging emails SPAM.
Many thanks for your time.

M93p AMT not recognizing DHCP or static IPv4 address

Hello,
We recently bought 3 M93p 10AB0010US systems for a pilot, with the potential to buy 350. One of our requirements is functioning Intel AMT. We are currently using M92p systems with Intel AMT v8.x with no issues.
The M93p uses Intel AMT v9. When configured to use DHCP and share the FQDN with the host, Intel AMT communicates with the Intel Management and Security Application Local Management Service to identify the DHCP IP address and configure AMT with it.
This is where the problem seems to be. According to the status applet within Windows, the Link Status is "Link Up", the MAC address listed is correct, the IPv4 Mode is "DHCP", but the IP address listed is 0.0.0.0. On the local system, I can bring up the web UI for AMT and access (guessing it is using the loopback adapter?), but it is not accessible remotely because AMT is not intercepting the 16992 traffic targeting the DHCP address.
Initial, unsecure configuration is being done using a USB key configured with Intel SCS 8.2. It is the same config we used for AMT v8 devices, and seemingly works as the web UI is accessible, just not remotely due to the DHCP issue.
Any ideas? This obstacle is potentially preventing us from doing a pretty big hardware upgrade until we can resolve it.

Hallo, wir haben genau das selbe Problem. 2 Systeme M93p gleiche Problematik. Und es scheint System zu haben das Lenovo sich dieser sache nicht annehmen will. Wir haben aktiv einen Fall offen mit der Fallnummer: 012R512
Laut der Meinung des Vorgesetzten kann das Teil nicht unter Garantie getauscht werden da es nicht defekt ist.
Ausserdem ist AMT ein Intel-produkt, die Version die wir hier haben ist so gebaut nur mit unseren Treiber automatisch zu funktionieren. Wenn sie dieses ändern oder
speziell anfertigen möchten, wäre es vielleicht mehr sinnvoll mit Intel kontakt aufzunehmen. Wir unterstützen dieses nicht.

DNS/DHCP Managment Console- IP Addresses not releasing

Hello,
I have added a new subnet on our network so we can add more wireless devices (iPads, Cellphones, etc. are all now needing IP addresses)
Everything is working fine except that the addresses are not releasing after 3 days. If someone with a Laptop comes into our building with a cell phone or laptop they are picking up an IP address automatically. Then once they leave (and the 3 day lease time expires) DNS/DHCP is not making that address available for another device.
Now we are quickly running out of local IP addresses on this new subnet. How can I get DNS/DHCP management console to hand out previously used expired IP addresses to new devices?
Thanks in advance!

Hello,
No we haven't run out yet so that my very well be the case.
We do have two subnets in the same building .30 subnet and .32 subnet
They both work, and any client can pickup an IP on either subnet.
The .30 subnet was the old one and the .32 subnet has just been created. Now all new clients pickup an address on the .32 subnet.
Is there any way to figure out why all the clients want to pull a .32 address now?
Thanks

IMessage getting "Not Delivered" error, Message Send Failure

I upgraded to ios5 on my 3GS last night, seemed to have no problems, no errors. When I try sending a text another iphone users, it defaults to sending an iMessage, but then says "Not Delivered" in red, with a red exclamation point next to it. My daughter, on the same network and same house can send imessages to me, but I do not receive them.
In my settings, I've tried turning iMessage on and off, tried setting "Send As SMS" both on and off, no changes. "Receive At" has my phone number, and my apple id email address. I've tried restoring and reinstalling ios, restarting the phone numerous times, nothing seems to work.
Any ideas?
Thanks,
Nancy

I'm in the same boat with my new 4S. I installed 5.0.1 last night and it was working fine until this morning. When I woke up, I tried to send a text message with no luck. iMessage works fine, and I can RECIEVE text messages. Just no dice on sending any. At all.

Let me take your side here. Call verizon billing and tell them you are cancelling the phone and service since you have not received it from Fedex. Verizon requires you to sign for their shipments from Fedex. The carrier then tries three delivery attempts and then sends the package back to verizon.
If you paid by credit card call up and dispute the charge, since your 14 days of previewing has not technically started as to return it within that time frame, just cancel the whole order. Make sure Verizon does not try to bill you .
Dispute, dispute and dispute.
You could have went into a verizon store and got your phone imediately instead of being shipped.
A lost or stolen phone not signed for by you or authorized person is verizons problem and not yours. You don't owe verizon for service not provided or the phone that was not delivered. Call your bank or credit card company and have them remove the charge.
