DNS timing out?  Try specifying IP numbers for the servers using a test
account to see if that helps.

ServerB is doing nothing more than routing to ServerA.  SeverA is dialed to the internet, it too has quite a few users doing the same, sending, receiving emails and web browsing.

Looked in /var/messages and there is nothing indicating any kind of problem.  I've noticed that I cannot ping the dial-up connection to the other ServerB nor route anymore.  If I kill the processes for ppp and pppd and restart the services and dial-up everything is okay for another half hour or so.
