Hi bbrown, actually it's not a requirement.
It's done for a more practical approach. The usual way, the 1st user would open Navision, post something, then close. Then the 2nd user would open Navision, post something, then close. And so on...
Your idea of using multiple RDS's in the same machine sounded good, and I could really think of a better password policy together with our AD Adminstrator, and then use Windows Authentication. Thanks! =D>
But, regarding the changes on system tables, I'm still open to any comments... :-k
