ninnox, Tthe dns solution works perfectly. i don't know how to thank you for it. The second solution you describe it's not working for me, not even the shared folders are available, it gives a random ip that makes no sense and a diferent subnet mask also. Before sp2 it was how i do it, but now it simple doesn't work. But it's fine now, i've set it up manually (like it even better ) with the ips i've mentioned before. Tks alot to everyone for replys, and tks ninnox for solving my problem.
