[Samba] error first logon attempt

[Kees van den Bosch / Skool Automatisering]

I am using Samba as a NT domain. But I encounter a problem:

When I successfully joined a windows 7 workstation to my Samba domain, and then set the registry keys for autologon (AutoAdminLogon, DefaultUserName, DefaultDomainName, DefaultPassword and ForceAutoLogon), I get an error after the first logon attempt:

"There are currently no logon servers available to service the logon request"

However, after exact 2 minutes the workstation does login without touching it! After this first login the error never appears again.
How can I solve this error,  someone familiar with it?


Server:  Centos 5.5 (final)

Samba version:  samba3-3.5.11-44.el5 (installed rpm)
