Hello,
I hope anybody can help me with the following tough problem. We are
running a samba-server (3.0.7) for providing fileservices for our
constructions department. Since 2 Weeks we encounter problems with 2 of
our workstations, running under win xp professional (The third xp
workstation and the 2 running under win2k do not have this
problem). The cad program tell's me, that it can not set the write
lock correct. It seams to be a problem with oplocks because the only
thing I can find in the log is the following:

Closing connections
This error does only appear at some files. Others work just fine. The
error occurs everytime the file is accessed. After a restart of samba
the problem went away for about an hour but came back after that. :-(
Thanks in advance for any help or info where to look for a solution.
