And can you copy files using Explorer or other file manager software?

It would appear that your code is building an invalid UNC path, or a path that doesn't exist. Move the code that builds the path to its own variable so you can see what it's building, then you can troubleshoot it better.

Dim destinationPath As String = String.Format("\\{0}\{1}", mdChecking.PublicServerName, shellCommand.Trim.Replace(":", ""))
File.Copy(BakFileName, destinationPath, True)

Now, the other part of the problem is are these two machines working in a Workgroup in an Active Directory?? If Workgroup, you've got problems. Each machine matintains its own list of user accounts and does NOT trust the accounts of another machine. If in Active Directory, then is each machine in the same Domain?? Each machine in the domain will use and trust a central list of user accounts.
