I think besides an opinion, I *did* give you a solution: A service account usually doesn't have mapped drives as those are stored in the user's profile.
Use a UNC path instead.

Imar,
It seems you are aware of how to use mapped drives or you wouldn't have mentioned it. A further reason for using a pathname instead of a UNC, as you call it, is because I need to use the Win32_Direcotory function and a subset there of Win32_ChangeSecurityPermission. Win32_Directory requires that I supply it with a pathname e.g. "C:\Users\User1". I have tried using a UNC but to no avail.
Please advise.

It's the other way around. I mentioned UNC paths because I know mapped drives cause problems.

The only way that *might* work is to log in with the account you're running the service under. Then map the drives for that account, log ou and configure the service to run under that account.

Not sure if that works because I don't know if the service "logs on" when it runs, so I don't know if the drives become available.

Other than that I am out of ideas. Sorry. I have always used UNC paths.
