There's the situation.

We have a room where we give some courses. In this room, we have 25 computers where we fix the ip address on each.

We create an account called "Formation" and put the 25 ip address in the Address Restriction to restrict this account to this room. This account also use the DLU policy. Each people who attend to the course, use the same account (Formation) to log in.

Everything work fine with W2k, but some computers are in Windows XP SP2 and those computers don't log in with the ip address fixed. If we remove the ip address we can log in, without any problems.

Client version : 4.91 SP4.

Any clue about this ?
