win2k & smb

I have samba set up on my linux box on a 10mbit subnet.  I have my win2k machine on a diff. 100mbit subnet.  i have the linux box mapped out in "lmhosts". i can see the linux machine when i do a search for it netBIOS name on win2k. i can mount the win2k machine onto the linux machine.  i have client and flie/print sharing installed on win2k. i cannot mount linux onto my win2k machine: error message: the account is not authorized to log in from this station.   there are no permissions set on my samba server.  i can mount it onto my win95 machine no problem. n e help would be greatly apriciated.
