[Samba] Semaphore Time Expired

[Derek Smith]

I am running Debian 'woody' with Samba 3.0.2 and am having a sparatic 
problem on my network.
Some users will suddenly lose their connections to the samba shares and 
when trying to log in
to the system again will get an error that windows cannot locate their 
roaming profile - "Semaphore time period has expired".
It seems that if they wait for about 15 minutes they can then successfully 
log back in.

Please help. I am not even sure where to start. I have been googling for an 
answer for about a
day and while I have found other people with the same problem, I haven't 
found many solutions.
