Unable to connect to Win2k server after installing ISA

I have recently installed the Internet Security and Acceleration Server on a Win 2000 Server with 2 NICs. The LAT seems to be configured fine and the clients have no problem using the ISA server for web browsing. I am also able to connect to it internally using the Advanced Terminal Client. In addition, I can ping it by name as well as by the IP address.

Here the problems: I cannot connect to it using its NetBIOS name. When I go to Start->Run and type in the \\<server_name>, I receive "the network path was not found" error. Also, I cannot share anything from the ISA server since the "Sharing..." option is not available when I right-click on folders.

It is vital for our network setup that we can connect to the ISA server internally using NetBios. I've been struggling with this for over a week and would really appreciate your help.

Thanks for your time,

Alex.

ISA usually disables file and printer sharing.  Go to your network properties and see whether File and Printer sharing for Microsoft Networks is enabled.  Enabling this is a security risk.

the the \\name points to the nic that is filtered?

so you need the ports 137-139 and/or 445 if it's win2k only. Can you check this?

afridman it seems to me that if you stop ISA & the problem is still there geoffryn is probably right.. If you stop it & the problem seems resolved franka is probably right..

I've stopped ISA and the problem was still there.

However, there is no File and Printer sharing for Microsoft Networks in Win 2000 Server, remember? It's only there on Win 9x versions. All NT/2000 machines have that property enabled and there is no setting available for you to change.

Also, I used a port scanner to verify the port availability. The ISA server has port 139 on the internal NIC open.

The internal NIC is not the one being filtered. I should be able to do everything from the inside.

Ouch! Sorry guys, didn't verify this. I didn't find the File and Printer Sharing and assumed it was never there. Everything works now. Thanks!
