the name limit for the local computer network adapter was exceded

Do you have a netdiag output? Is the server pointing to itself for DNS?

 

[psasu]

First check the server ip configurations ie it should point to itself for dns and reboot the server and let us know what happens.
Is the brain 2 computer a dc or a workstation? if you have two or more dcs make sure you check the ip configurations and reboot all the dcs

 

[mlichstein]

You can save yourself from reboots by running these two commands after making any IP changes:

ipconfig /flushdns
net stop netlogon & net start netlogon

Hi,

Thanks for your input - I'd gone ahead an rebooted the server last night before waiting for replies, and the problem has dissapeared.

I still have no idea what caused it tho. I'm guessing the it's to do with the network adpater getting all crossed up rather than a DNS/AD issue.

Brian2 is a workstation; workstations winning elections is something that actually happens quite a lot - is this not right? Any idea what I can do to stop this happening?

Sounds like you have XP Pro workstations. If that is the case, you need to disable the "Computer Browser" service on your XP workstations. This will prevent them from calling for an election.

Help! I've fallen and I can't reach my beer.
