Hi all,
After searching, digging and testing I have no more ideas to try. I explain:
I'm trying to setup a small local File Server (Ubuntu Server 10.04 and Samba
3.4.7) After looking at the forums about the configurations of Samba and
Windows I managed to get all the network running at 99%. The remaining 1% is
that the connection to Samba from Windows 7 is performed intermittently.
XP pcs have no problem accessing, mount drives, read and write to the Samba
server. It seemed that Windows 7, after edit various, either. But after a
few minutes (sometimes seconds) Windows 7 is no access to the server more,
and after a few minutes reconnects.
The access is done with user authentication and permissions are handled in
Ubuntu
I record some traffic with Wireshark, but I'm not have enogh level to draw
conclusions.
Best Regards!
