[Samba] Session setup with machine account

[Christoph Klein]

Hi,

Our Samba Servers are getting slower and slower. Even opening the
context menu on some files take 5 seconds. My log file is filled up with
messages like:

FWI-PARIS is the computer from which i'm connected with the server.
It seems to me, that all these SESSETUP_AND_X calls make my server
slower. Is there any way to stop windows (XP SP2) issueing these calls?
Does anyone of you have similar problems?!
