Facing a problem after joining a station to a domain, I had a hard time finding the solution on the internet, now I found it. Perhaps there are other solutions but this works like a charm.
When trying to login to other workgroup's shared folders from a domain station, a popup error message says:"computername 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. The username was not found..."
Something like that.
The solution is to create a batch file (ie. network.bat) with any text editor such as notepad and place it in the startup folder so everytime windows restarts, it will run this command:
(When you see forward slahes like -> '//', please replace it with two backslashes, LifeType's bug prevents me from displaying the right slahes; There appears to be a fix, which I might get to it later)
net use //nameofdestinationcomputer user:administrator
