Windows – Map a network drive from a Mac network on the PC

Have you tried to mount the folder using smb://?

In OS X Lion, the Finder will mount the volume named Sharepoint on the SMB server myserver.mydomain.com, and open a window showing the contents of the directory named Folder2. Note: You must have permission to read Sharepoint, Folder1, and all other directories in the path to Folder2. Otherwise you will see the message "The folder can't be opened because you don't have permission to see its contents."

In Mac OS X v10.6 and earlier, the Finder will mount the folder named Folder2 and open a window showing its contents. You only need permissions to read Folder2 in order to mount it.

Additional Information In OS X Lion, the mount_smbfs command can be used in a Terminal window or a shell script to replicate the Finder behavior in Mac OS X v10.6 and earlier.

For more information, type man mount_smbfs in a Terminal window.

Finally got it to work by invoking:

net use P: \\SERVER\folder /savecred /persistent:yes

at the command prompt.

Checking Windows Credential Manager afterwards, the correct network address of my server was actually SERVER.DOMAIN, wherein DOMAIN was a domain I set arbitrarily on my OpenWRT router. Apparently, net use makes things easier by detecting this automatically for you.
