Last week, I went ahead and upgraded a client's Windows 2008 domain controllers from SP1 to SP2. Reason, I'm always staying ontop keeping their Linux based NAS boxes working nicely with Active Directory etc, and thought it was a quiet time to update stuff across the board.

As it turns out, once Windows 2008 was at SP2 level, the NexentaStor 2.0 box now doesn't work on CIFS shares. The only way to access them is to use the "guest" login (a login box appears when you browse to it from the network).

Viewing the CIFS server log - got this:

Aug 20 13:27:37 server1 smbd[352]: [ID 526780 daemon.notice] Failed to establish NETLOGON credential chain
Aug 20 13:27:37 server1 smbd[352]: [ID 871254 daemon.error] smbd: failed joining domain.lan (UNSUCCESSFUL)
Aug 20 13:27:37 server1 idmap[335]: [ID 694198 daemon.notice] Configuration unchanged

After sending an email to support, they pointed me to:

http://www.nexenta.com/nexentastor-relnotes - Scroll down to v1.1.9 - known problem

and http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6850508

I have been told this will be addressed in September... or we can roll back to SP1 on the domain controllers! WTF, I guess this is Sun that is just slow to move on a pretty big bug. :(
