Samba Error " No login servers available to service logon request"

Hello List,
I tried the Samba users list and got absolutely no feedback so I am
trying here. This is quite urgent as it happened twice already today.
The first time I rebooted and it worked for maybe 2 minutes. The second
time I deleted the /var/lib/samba/mutex.tdb file and restarted Samba.
This original message is from the first time it happened. Can anyone
help me to fix this issue? All the Samba data is served from this
machine. There must be a technical mistake I made somewhere along the
way but nothing I can pinpoint. I will gladly upgrade samba but I think
that it is not the problem. Any assistance is greatly appreciated.

James



My samba server stopped allowing access to shares this morning. It gave
some errors. Has anyone seen these before? The OS is Fedora 9 and the
version is...
Version 3.2.0pre3-9.fc9
I am using ADS security for serving shares. 
Domain controller is EXAMPLEDC.EXAMPLE.CORP

Looks like it is saying no login servers in client log but, there are
two listed in smb.conf and they both replied to a ping when this
happened.
I tried restarting smb but it did not help. A reboot cleared up the
issue but I want to get to the root cause.

There are some strange lines in the smbd log as well(bottom). 

Any help is greatly appreciated. Can I avoid rebooting this to fix it if
it happens again. Or better yet can I permanently fix it maybe upgrade
Samba. I saw a previous post where raising amount of processes allowed
per group was suggested.

Thank you
James
