I have a network share to a Windows Server 2008 file server, that is used to view all media files on every computer at home. I've been able to access this share on OS X (10.6.2) for a year now, without problems.
This morning, however, I was unable to connect via OS X. I tried rebooting, and connecting to it's ip instead of the computer name, to no avail. A friend recommended deleting the .DS_Store files on the share as it might cause problems if this file is corrupted, but this didn't help either.
I can ping and RDP to the server. I can also connect to shares on all other computers except the file server.
I'm at a loss for what's caused this, and how I can fix it. I've haven't touched any settings on OSX or the file server in months, so that can't be it either.
