I have 4 offices, single domain. The file is not large and to register the .dll would be a one time deal. I'd rather have the users register the file using their local logon server rather than GTB1 across the WAN. About 400 users total. I don't think any of the Kix switch will work as it is a Shell command and the tqcrunas then has its own switches...But if that's the easiest way it will work that's fine too.
