Hi guys,
im having an issue with a bunch of users (40) who log on at 4PM, all of them are struggling to log on OR off taking upwards of 40 minutes. All the users (1000) get their profile and redirected documents from the same locations and seem to be fine however they are logging on from 8am onwards. Now i believe possibly that the server is maxing out its number of of sessions. I have perfmon running against it today and i can see i am averaging about 510 active server sessions.

The question i have and what Google doesnt seem to be able to answer is what are the limits? I cant find any technet article to say the max is say 600 sessions so i have no idea if its running within its limits or not.
