i have a dell windows 2003 server in a workgroup enviroment. dhcp and dns are coming from a router. the server has a static ip, gateway, and dns assigned to the nic .
the static ip is for the terminal server which is running on the machine. when the machine is restarted the nic loses all conectivity (cannot ping router, browse internet). i can disable and reenable the nic with the static numbers and everything works fine until the next restart. i have upgraded the broadcomm netextreme drivers to the latest 14.0.0.7. i have disabled the firewall service on the server.

Try Winsockfix which will reset the TCP/IP stack to Windows Defaults http://www.snapfiles.com/get/winsockxpfix.html
It says it's for XP; but, works fine on 2K3

If you want to be safe and have free rein, you should read this: http://www.computer-help.net/Best-Registry-Backup.html

Then, if Winsockfix doesn't do it, the normal, next step is to uninstall the NIC's in the device manager and reboot so they are redetected.

Have you checked for malware or virus? Also how about a bios update?

My next two suggestions were to get a registry backup and to then uninstall both NIC's in the device manager.  After a reboot, they will be redetected; though you may need to set the static ip (etc) again.

Sounds like it could be a negotiation issue.
What type of switches?
Are you running spanning tree?

the router is a linksys 600. the server is connected to a dlink switch via 2 broadcomm gigabit nics. all the other systems in the office and no problems with network traffic.

broadcomm gigabit nics.

How are they configured?
Load balancing,failover?

Are the NIC's set to auto or are they configured differently?

What is the model number of the Dlink?

What is your DHCP server?
Router or Windows?

I wonder if the server is switching to gigabit mode and killing it connection. Try switch to 100 base and see it it will stay connected.

He says it's connected to the dlink 10/100 switch.

Messing with the duplex settings on a gig nic is a very bad idea.
Everything needs to be set to auto only.

If he's got the both nics plugged into the same switch at the same time without it being set for load balancing or failover,he will have issues.

I would personally plug into the gig ports on the router as a test as it is a more up to date chipset than the dlink.

As for dhcp and dns,I would use the server for that.

M$ stuff can act funky at times unless you follow their best practices standards,of which that is one.

Check in settings for rdp/ts host. You can specify which nic should respond to RDP requests. Try setting it to 'all' instead of a specific NIC if possible as this is known to have issues.

If that doesnt work, could you describe what you have to do to get the NIC working following a reboot please?
Can the server ping other devices while not responding? What does ipconfig /all say about the NIC while its not responding?
