I have a problem with Windows 7 Home connecting to samba on linux server. It's worked fine for a year and without any changes in configuration or updates it suddenly stopped working. The strangest thing for me is that it stopped working for no reason that I could think of. After a few minutes after trying to connect I get:
\\ip is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
Other computers in that network (XP machines) connect to samba without any problem.
I've tried adding LmCompatibilityLevel as described here: http://www.tomshardware.com/forum/75-63-windows-samba-issue , but it didn't help.
