hello XP is driving me banana's i have 2 serious probs with it and i hope to find any helping hand here :-) :-) i have a domain running on win2k server no problem with the domain now every time i join a XP-Pro ( sp2 ) workstation to the domain the workstation lost his dataconnection from the domain ( the nic is ok ) i can't brows the domain any more , but i can ping it normally i can't access files and more when i check the control leds on the network switch they are on so the connection is there. whats wrong ??? second part , it's almost the same but now with a SQL server it's realy frustrating every 20 min the connection to the database has been lost and this problem is only a XP problem. and it's not workstation related as we use several types of brands thanks for the helping hand Marnix
