[Samba] wierd performance problem

[Sam Barasch]

Distinguished Ladies & Gentlemen of the Samba list, I implore you to read 
further.

We have two samba servers, on one of them we have a strange problem.  After 
logging in and mapping network drives, if you open 'my computer' the 
machine hangs for 15-20 seconds before showing local and network drives.

On our other samba server, we don't have this problem.

As far as I can tell, the only difference is the IPC$ share.  PCs that log 
in to the domain with the performance problem get the following error 
message when trying to open \\server\ipc$ from the 'run' menu:

\\server\ipc$ is not accessible.

network access is denied.


My suspicion is that win2k machines try to access ipc$ and get denied, then 
wait for a timeout, and display the network drives to the best of their 
ability (accurately & completely BTW)

Any advice or commiseration you can offer would be greatly appreciated.

TIA
