Windows 2000 Server, terminates connection from a PC on a different domain after a set amount of time

I have seen a tech note on Micorsoft's site but having a hard time finding it, I'm just not typing in the right search.
My issue is with Server 2000, it is on domain A and a PC connecting to it is on domain B.  After about 20 or 30 minutes of no activity the server terminates the PCs connection on domain B.  Does anyone have the article ID from Micorsoft's site on this or have instructions how to change this setting?

If you are using a RRAS/VPN connection, you can control this by changing the policy settings on the RRAS server or router.  Could you please describe what type of connection this is, so that we can answer more accurately?

Sorry I was I didn't describe the connection.  It is simple star topology with managed switches.  The Server is a simple standard server not providing services other than diskspace.
I am not sure what you are doing but you could setup a trust between the 2 Domains.

The trust has been setup, but this has to do with the server being on one domain and the PC accessing the server is on another.  Since the PC is on a different domain there is a default setting on the server when a connection from a different domain will be terminated after about 20 minutes of no activity.

I think I found the answer.  Since it had been so long since I have seen this I forgot that mapped drives were involved.  Here is the article:
