'\\.\PhysicalDrive0': *** Can't be Locked (error 5)!
'\\.\PhysicalDrive0': Error returned (-10). The drive can't be locked!

So I'm wondering how to unlock the drive. Or even if that's possible. I have a funny feeling I'm doing someting real dumb...

Some more background...
The computer are both connected to the same home router (so they have IP addresses like 192.168.1.2) but they are not on the same Workgroup. The server is my work laptop connected to an Active Directory account and I don't want to have to take it off the AD account and move it onto a Workgroup. I've been using FTP to trfx files between them but mounting the drives would be so much nicer.
I also didn't use the explorer.exe to "share" out the drive (there is no little server hand under the HD icon). Is that a problem? I didn't share out the CD player in explorer and I was still able to mount that via StarPort to StarWind... so I'm guessing that's not a problem.
I didn't modify the config file except to add a login name and password. I did everything else using the UI.
Thanks,
Chris
