samba - Jan 2015 - Joined machine cannot mount share, others can - strange

I run a Samba4 AD and joined a Synology NAS running Samba 3.6.9. I can 
access the shares using smbclient or mount -t cifs from all Linux 
machines (usually running Samba 3.6.6 clients). I can mount the shares 
from WinXP home and Win7 home.

However, with a Win7 Ultimate machine joined to the AD most of the time 
it doesn't work. I can logon to the machine with my AD credentials, but 
I am prompted to re-enter credentials for the shares, which I'd expect 
to just work since I'm logged on to the Domain. And of course the 
freshly entered AD credentials are also rejected.

Most of the time it doesn't work means: I've seen it working, but in 
general it fails.

Thanks for your help,
  - lars.

Have you tried to map the same network share with different user's
credentials?

I tried to map the share with the same credentials. However, as it seems 
things are getting worse. I cannot login to the Win7 Ultimate machine 
anymore.

Since the AD also serves LDAP and Kerberos for the Linux world at least 
these basics should be up and running - and were running for a couple of 
months now.
