Problem with W2K -Login

[epn]

Hi all,
my PDC under Samba works fine (with Win9X).
Now I try to login with W2K.

Sorry, but I don't understand this.
First adding the account to the UNIX-password-file
# adduser -d /dev/null -s /bin/false <ntmachine$>
Second adding the smbpassword
# smbpasswd -a -m <ntmachine>

It doesn`t work !!!
I Have Samba 2.2.0-15 and W2K sp1 !
The error message from Windows is:
"To many procedure calls"

I can't see the Domain-PDC in the neighborhood.
Ping to the PDC is successful.

I think I forget something ???

Thanks
Sebastian Wern
