I have a 2960G-48TC-L and connected server with BCM5716C card. This server is runing Windows Server 2003 and serving DHCP. When the server is started the Netlogon service reports an error indicating no domain servers are available, DHCP service fails also. Netlogon starts however DHCP does not, but I can manually start it without a problem. It's as though the network connection has not finished initializing for some reason, however in the event viewer I see the NIC has completed it's connection. If I plug the server into another Linksys switch it is able to startup without these errors.
I'd like to connect this server to the gigabit switch. Should I upgrade the IOS? It is currently running 12.2(25)SEE1. If so which IOS should I upgrade to and anyother concerns I should have?
Thanks for any help you can provide.

Just a quick check - have you enabled "spanning-tree portfast" on the port the server is connected into ?

Not sure. It's been a while since I've config thru the CLI. I've recently only been using the GUI. What is the easiest way to determine this?

I'm not familiar with the GUI but easiest way for me would simply to do a "sh run" and check the config for the relevant interface.

Ok, thanks for your help. I looked at the running-config and for that port I only see the description I gave t
he port in the GUI. I don't see anything else associated with that port or other ports, exce
pt for the uplink. It had some additional info.

Alright, it appears enabling the port as a desktop thru the GUI added the appropriate settings. It added the enableportfast setting. Upon booting the server no problems with connectivity.
Thanks for your help,

Hi James
Desktop smartmacros will include the "spanning-tree portfast" command specified by Jon.. Apart from this, it will include all best practice configs for a end user PC/Server connectivity like - bpduguard enable (to prevent spanning tree instabilities), port-security configs, switchport mode access, and so on.. Incase you need to apply these commands on CLI, you can use the following:
switch1 (config) # interface fast 0/1
switch1 (config-if)# macro apply cisco-desktop
and automatically you will have these commands applied:
switchport access vlan
Hope this helps.. all the best...
