samba - Oct 2012 - A device attached to the system is not functioning(samba 3.6.3 + OpenLDAP)

Today's morning I got "*Domain not available*" on all windows xp 
machines(domain logon working only for users with cached profiles)
I tried to rejoin machine to domain, but when I try to join, error "*A 
device attached to the system is not functioning*" occurs
Here is error log when I tried to join http://pastebin.com/MCHKMjmL
"*Re-using invalid record*" looks suspicious, but I don't
understand how
its related to my problem.
I'm using samba 3.6.3 with OpenLDAP

My samba config: http://pastebin.com/BKLVBeWv

Also, I done absolutely nothing to server before error happens(just 
reboot 2 days ago)

A lot of times I see errors like this to be a browsing problem where
the client does not know the ipaddress of the server. Does your client
have a wins address in its config?
