Remote connections multiple locations

SOLVED

I have a customer with 2 remote locations using Sage 2018 sp3 Advanced.

All users at one of the remote locations connect to the terminal server and run fine.

A single user from the second location (they only have 1 user) always gets a prompt from UAC "to continue type administrator password".

Another user on a laptop also gets this prompt.

What would cause this?

All users have full access to the Sage folder on the server.

As always thanks for your assistance
