Tiger and AFP Windows 2000 Server

Well, I have a Windows 2000 Server at work. Under Panther connecting to it did and still does work fine using AFP, but now under Tiger I can not connect and I receive and error -35 Some file or object could not be found.

Now I can ping the machine and even access it through samba, but I cannot launch applications through a mount 2000 server drive unless it is mounted using AFP.

Any help is appreciated.
