[Samba] WinXP lost connection to Samba fileserver

[Petr Vyhnal]

Hello,

I have big problem with WinXP clients on my network. I tried to find 
some solution via google, but without success. I have Win2K Server as a 
PDC and Linux machine as a fileserver. Linux box is joined in domain and 
all users are authorised against W2K server. When I start WXP client 
everything works OK. But after about 30 minutes client workstation lost 
connection to Samba server and only way how to get it working is to 
reboot workstation. Samba server is visibe in network neighbourhood, but 
when I try to access network drives, computer freeze for long time and 
few minutes after show me login dialog or message that drive is not 
accessible. I really don't know what I can do with it.

Thanx

Rudiik
