Trying to map a networked drive from one IP subnet to another:
I have 2 subnets connected to one another through a Sonicwall. The firewall is configured to allow access from subnet to the other (Configuration verified by Sonicwall tech support)
I can RDP from a domain network to a workgroup file server from any PC in the domain.
I can map a drive on the workgroup server from any other server on the domain running Windows 2003 or PC on Windows XP.
The folder I want to map is shared by "everyone" in full control
When I try from a Windows 7 PC I am presented with the login for the Workgroup server administrator, I enter the password and it rejects it.
Why would it work with XP and 2003 and not with Win 7 or 2012 ????
