I already postet the output in the case. But I attach the full output
to this mail, no problem ;-)

Yes, every time, no matter from which Windows Client I try
(I've tried with 2 WinXP, 1 Vista and 1 Server 2008)

No, as you maybe have seen in the bug report, I did a truss on the smbd
process and attached the output to the bug report. the smbd process
remains the same.
In my case,

Nope, no messages. I can't find ANYTHING useful which makes easyer to
debug this problem. And in addition to that, the most annying thing is  
to
reboot the server. A restart of the smbd process does not help. After  
the
reboot the cifs service is up and running and all is fine again.

Again, what I do is:
- connect a local drive name on the windows host to the cifs share
- pull the network cable out from the Windows Client
- try to access the share (which obviously wouldn't work)
- reconnect the network
- try to access the cifs share

I've noticed thos problem by trying out the offline folder feature,  
which
worked fine except for a network interruption. At first I thought this  
was
a offline-folder bug. But it's the same with a simple access to a shared
folder.

I know, I didn't provide this much useful stuff to you to debug the  
problem.
I'm perplexed about this problem...
BTW: would a explorer help? Does the Solaris Explorer work on
OpenSolaris? I've never tried this...

Thank you
