I have the same with several systems.
I increased the IRPStackSize to the max of 50 dec. and noticed some
improvements. Other things that seems to be of influence are the
USB-devices plugged in (blue screens at plug in!). With the Vista
systems used as "server" I noticed the problem after some MS-updates
around jan/feb 2009. The problems occurred with antivirussoftw. of
Symantec, McAfee and AVG (free and the Internetsecurity version). I
understand that at the time of the above mentioned MS-updates there were
changes to prevent misuse of systems by malware etc. so that points in
the same direction for the IRPStackSize. Unfortunatly the max is 50.
IP chimney and other suggestions didn't work either.
It seems that for some systems it's more problematic than others (I
experienced it with HP and some self-builds). Even had big problems of
intermitting network contact with HP-multifunctions, but after the patch
for connection-stability that problem was solved. At the moment I reboot
the Vista "server"-systems at nighttime.
Windows7 doesn't fix this problem. Some systems with the same software
and configs don't seem to have any problem, but I can't see any logic in
it for chipsets or other hardware other than that some HP-systems seems
to be extremely sensitive for this issue.
btw Lowering the number of shares in combination of maximising the
IRPStackSize made it a little better for some systems while others
functioned OK.
Anybody with a solution?
