W2k LAN Internet Connection Problem
Windows 2000 Server with Windows 2000 clients:
I'm baffled at the moment and could really use some help. I'm having Internet connection problems on the LAN, but there's no pattern to it. Most of the computers connect just fine, but two of the computers, that have connected fine up until this point, have stopped connecting to the Internet. However, both computers are connected to the LAN okay and can access LAN resources without any problems; it's only the Internet these two computers cannot connect to.
The way we're set up, we have a domain controller that handles Internet access for all clients. There's no hint of problems in its error logs.
I've tried the following to troubleshoot:
1) Through the command prompt, I've used ipconfig /release and ipconfig /renew (this used to fix the problem before).
2) Rebooting computers
3) Changing connection properties to both "detect DNS automatically" and manually using the domain controllers ip address.
None of the above have resolved the problem. Keep in mind, all other computers are connecting with no problems, and these two were connecting -- no other strange activity has occured to give me any hints as to what the problem is.
Can anyone throw me some ideas?
