Oh, I spend all afternoon trying different things.
Also I had problems with my mail-client, loading websites, in particular all things that involved pwds bankin etc.. We Nmapped the network from an outside server.. I just wanted to make sure HE is my problem and that there is nothing wrong with either the client or my connection with the server.
I complained with my landlord today about this and since I also do work where discretion is VERY important...
So I'm waiting for him to take down the filters.
ALSO
A few minutes ago I suddenly could login, without restarting my client while just seconds (and a 100 tries) before said my pwd was incorrect
So I'll map the network again.. and see if he fixed it
