We have 4 TS in our domain, all 2003 sp2. Each server has the 'restrict each user to one session' in tscc set to 'yes'. There was a time when, if a user logged in to TS1 then TS2, with the same user id, it would disconnect the TS1 session. Now, they can open up a multiple sessions with the same user name.I'm not sure what if anything changed other than required updates...??i removed a program that was placed the the startup group of one user as one thread indicated that a startup program may have some effect.. that did not work.Please, if you have any ideas or suggestions, on how to restrict each domain user to one logon in a domain, that you forward them to me.appreciated.thanksmarni1 person needs an answerI do too
