Does it happen with every windoze client?  Which flavor of windoze? 
 (many parts are *not* edible, but they *are* broken)

Otherwise it sounds like a bad binary/lib problem.  I've had samba 
1.9.18p8 running on RH 4.2 (kernel 2.0.30) for up to 150 days at a 
time with no problems.  That's about as long as the power to the 
building stays up - we have a couple small UPS's on stupid windoze 
boxes, but I can't have one :-(

My off the cuff answer (not having played with samba 2.x yet, so 
take it for what it's worth) would be:  If you're going to use 
samba 2.x (with or without kernel 2.2x) you should stay up with the 
latest release (2.0.4b?) and always compile it yourself.  If you 
don't run it on linux, then try and get gcc for your OS and use 
that instead of the native C compiler.  And beware of glibc 2.1 for 
now...   There's also a small gotcha with respect to samba's 
configure on linux x86 thinking it's on a 64-bit system (that may 
be fixed in the very latest samba).

Hope this was at least somewhat helpful...
