XP logon to win 2003 domain

I get in trouble with my XP at work. I had to reinstall my computer and now I have several problems:
– long delay for domain logon,
– no shared printers available on the network (the search get no results)

I have to tell you that, I see the other computers on the network with their shared files and printers, but I can’t install a network shared one.
I have fixed IP for each computer on the domain, Netbios over TCP/IP activated, and testing from administrator account validated on the server (win 2003 standard server).
Any ideea about this delay and network printers sabotage ?
Thank you a lot ! razvan
