Can't log in to domain on some pc's

Hi all,

We have a SBS2003 server that does dns but a second server 2003 standard that is the dhcp server. Most pc's are fine, they connect fine every morning, some times if the pc is moved from one desk to another it will not log in any more. It claims the domain controller cannot be found.

I had this issue before and was asked to remove the computer from the list on the server under active directory users and computers, this worked a while a go but makes no difference now.

If i unplug the network cable, it lets me log in to the pc, i can then plug in the cable and the pc is assigned a network address and the user can access the server and the internet as normal.

If I assign a static ip address to the pc everything works well.

I think it has something to do with DHCP but not sure what.

any ideas?

Cheers,
Steven

When you look at the DHCP IP address does it point to the Windows 2003 server has the DHCP server?

Check to make sure the client points to internal DNS servers.

Remove the client from the domain delete the computer account then re-add.

I removed one from domain an deleted the computer account, when I go to join the domain it is not getting an ip address, it is self assigning one.

There is no dhcp service running on the sbs server.

So, here is the problem I believe the issue is that the stations are getting DHCP IP addresses from the DHCP server. Do you have another station that is not working properly? Check to see if it is getting a DHCP address.

At the moment all but two stations are working and getting addresses from dhcp server, one of the two that do not work was fine until we moved the pc to the other side of office, it is still plugged in to same network point although we used a new cable, I have tested the cable and used it on another conncection, if I move pc back to where it was and use original cable it still does not work.

It is as if the lease on the ip is up and it is no longer giving out new addresses.

I had a quick look before I left tonight and in the dhcp console the server has a blue circle on it, not sure what that is regarding?

Ah, ok that makes sense. Wish I had noticed the blue circle earlier.

Thanks for all your help.
