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 ????

The share you are trying to connect to is on the server 2003 box?

Try this:

Start Menu Type run or cmd in search box

Type: secpol.msc

Go to Local Policies | Security Options and choose the “Network Security: LAN Manager Authentication Level” item Set it to “Send LM & NTLM use NTLMv2 session security if negotiated”

I have a 2003 server on both sides and from the 2003 domain, I can map the 2003 workgroup. but not with Win 7.
I will remote into the system and try your suggestion asap and keep you posted.

Try adding a manual route to your workstation

IN one of my earlier jobs we needed to map a drive to a server cluster at IBM.  I added the route manually to each workstation and included the authenticating server name to the hosts file.

Regretfully, none of the offered solutions worked.
Apparently it can see the share since it prompts for login and apssword
However, I am still getting my login password rejected when I try to map the drive or access the share via file explorer.
