FreeNAS

Just had a server upgraded to 2008 R2 and I can no longer access our FreeNAS share, though the web interface is still available.

Using Run>\\freenas gets a "No process is on the other end of the pipe" error, and the logs on the FreeNAS box are full of "could not lookup domain group xxx" and "NT_STATUS_PIPE_DISCONNECTED" errors.

I've had a look around and there are a few suggestions that either seem irrelevant or I don't understand how to implement. Has anyone got any ideas before I just hook the disk out and add its contents to the (now) ample space on the new server?

The FreeNAS box is 7.2, btw. (I read there were problems with v8 and 2008/R2).

I wonder if its due to the fact that 2008 R2 increased the security around NTLM and Kerberos Auth, which broke many NAS units.

You can enable a setting in Group Policy to allow cryptography settings compatible with NT4 which allows it to communicate in the older methods as well which may cure your issue

Cheers. I did find a list of GPO changes someone claimed would help, but not many of them seemed relevant (and the ones I tried didn't help). I'll investigate further.
