I don't have much further information for you. Unfortunately I was instructed to back burner this item so I created a new vlan and pointed it to a 3640 for DHCP. Then I moved the affected machines into that Vlan. Here is what I can tell you. 1) The original DHCP broadcast is reaching the...

The IP helper command exists and is configured correctly.

I have posted more about this issue here: http://www.tek-tips.com/viewthread.cfm?qid=1411725&page=1 If anyone can help, I'll be eternally grateful. Thanks!!!

Well, the switches have all been restarted, and since the PCs can't get an IP, there is no mapping of MAC to IP. This morning I have new information though. I placed a Windows 2000 server on the network and moved DHPC to that box. Everything works perfectly. So there seems to be 3 things...

You are right, it did get cropped. I did put my laptop on the network and it had the same issue. I haven't put my laptop on the same Vlan, but I moved some of the clients that have been a consistent problem to Vlan 1, where the server is located, and created a small DHCP scope on that Vlan...

It appears from the packet captures that what is happening is the original layer 2 broadcast reaches the server, which is on another vlan, and then the unicast broadcast from the ip helper command hits the server. The server sends an ack, then a nack, but the nack reaches the client first, and...

Yes I have. I've got Dell and Cisco going nuts. We all thought this was impossible. ;-) Leave it to me. What I'm trying to do now is take Windows out of the mix. If Linux works fine, I need to get Microsoft involved. If Linux has the same issue, then it's a Cisco problem. Personally I...

Okay, I need Linux Guru. I need to be able to monitor DHCP similarly to the monitoring that is possible in Windows. We are having an issue with DHCP and I am trying to narrow down exactly where the trouble lies. Below is a description of the problem. Here is what I am dealing with. On a...

Yes, you are right. It is a 10/100 card. I tried setting the Intel NIC to 100 Full and set the port on the switch to 100 full. No joy. I've also used three different version of the Intel drivers. Thanks

I hope someone has an idea. Dell and I are pretty much at a loss. I do have some new info. I disabled the onboard Intel NICs on the server and install a 3Com 3c905B. Everything worked perfectly. Then Dell sent a Broadcom NIC and a PCI Intel NIC. When each of these are installed the trouble...

I have replaced 3 domain controllers running Windows 2000(Compaq DL380s) with new Dell Poweredge 2850s, running Windows 2003, and promoted them to domain controllers. They have identical settings to the Compaqs (i.e. name, IP Adresses, etc.)Here's where I have a problem. Some PC, all running...

You said it, nasty. ;-) As far as topology, they only have one domain controller. I came on board when they had numerous issues. This just seems to be the most severe, and therefore the one needing correction first. They do have Exchange 2007 that isn't working either, what a surprise, but I...

DFS errors I hope someone out there can help me. I am getting errors when I run DCDIAG. Below is the output from DCDIAG /D /V /C. I believe this has been caused by attempting to move the SYSVOL location. (This is not my server, but a clients server) I attempted to restore the missing FRS...

I have a Windows 2000 domain, running AD native. There are 18 servers and users experience this issue no matter where their homedrive is mapped to. I have about 30 users that log in RRAS daily. Every user has a home directory mapped in their Active Directory profile. If anyone, including...

I have user who log on mainly through terminals, and those have their rights severly limited. Sometime users who are in the terminal services group will log onto the domain with a PC. Then I need them to have more freedom on that PC. Is there a way to tell the DC that when someone has logged...

First let me thank everyone who responded. I really appreciate the input. I have figured out the trouble, and am working on a solution. Everything is configured correctly and the users are logging into the domain. Now, how about this new wrinkle, if I just reboot the computer it maps the...

We are in the process of changing from NT 4 to Win2k. Because of this it's hard to say what changes were made prior to the problem I'm about to describe. Windows 2K Pro machines logging into an NT 4.0 domain are not getting the drives mapped. I'm not sure if the login script is not running...

If anyone knows what those command line utilities are, PLEASE speak up! These users never actually log into the domain. The software package on their machines synch their databases and email. They never log in.

Here's the trouble I have. We set up 22 laptop computers with Windows 2K Pro and some special software. We then shipped these out to 22 salesmen in the field in 8 different states. We now realize we didn't install the printer drivers. Their local security settings do not allow them to add a...

If they don't, go to http://www.yahoo.com and sign up for free email. They allow POP3 access to their mail server if you agree to receive a certain amount of spam. I've found that it's only a couple of messages a month and well worth the hassle.
