samba - May 2002 - ads_set_machine_password: KDC reply did not match expectations

I am attempting to join Samba3.0-17 to an Win2k AD Domain and get the 
following error:
#usr/local/samba/bin/net ads join
#"ads_set_machine_password: KDC reply did not match expectations"

Any Kerberos gurus know of a way around this error?
