Yes, it's probably a permissions issue.
You'll likely want to try using impersonation so you're running under a user
account that has the necessary permissions. (Try setting it to use your
username & pw for initial testing purposes.)
Here's more info:

Also, you might try using the process object since it's a bit more robust
than shell. Here's an example:
Dim proc As System.Diagnostics.Process = New System.Diagnostics.Process()
proc.StartInfo.FileName = "C:\test.exe"
proc.StartInfo.WorkingDirectory = "C:\"
proc.StartInfo.Arguments = strMyArguments
proc.Start()
