samba - Aug 2014 - Windows 7 Pro/64 unable to contact domain controller

I have a number of systems running Windows 7/pro 64bit connecting to a 
Debian/Wheezy Samba DC. After one was rebooted today, I was unable to 
log on with a domain account, with the usual message about being unable 
to connect to a domain controller.

After logging on with a local account, I tried rejoining the domain but 
was unable - again Windows complained that it can't contact the domain 
controller. Re-did the Window registry settings change to allow Win7 to 
connect to an NT-style domain but still no luck. Same when I turned off 
the firewall. Rebooted multiple times in the process.

I can connect to network shares on the Samba DC (3.6.6) and can connect 
with SWAT using the NetBIOS name but others can't connect to shares on 
this computer.

Any ideas?

The actual error message is there are currently no logon servers 
available. It only seems to be happening to this machine. I can log in 
with the same account on other machines and I can connect to the PDC 
from this one.

The Samba logs show absolutely nothing happening which suggests that 
Windows is accurate when it says it can't find or connect to a login 
server / domain controller.

I've been through all the Google searches I can think of and haven't 
found much beyond the local security policy and local registry changes.

I can connect to shares on the computer only when I use a local account.
