Of course they do.  When we started as ISP years back a local BBS operator
shared a secret with me:
"I didn't change a thing on my machine" and "It always works on (the other system)"

Microsoft continued that with all their "Server OTL" messages.

More likely it's honking graphics, broken user boxes, filled c:\WINDOWS directories
and the like.  Diagnose the problem; do NOT believe the users wihout verification.

On the face of it, running a dialup is ridiculous so I'll assume you have
your reasons.  With 40 dialups you should look at separate terminal servers;
that's what they are for.  Hell, last time we rebooted ours was 2000-01-01 just
to be on the safe side.
