[Samba] samba 3.5.6 & win2k8 r2, session request fails

[Sys]

Hi

I've been trying to join a debian6 (IP: 172.16.0.180) box to a win2k8 r2 active directory (ORCHARD, IP: 172.16.0.200), without much success.

The settings for samba and kerberos are correct:
- and kinit works fine

The error string returned is: 'failed to lookup DC info for domain 'ARIAS.INT' over rpc: The network name cannot be found'

First i thought it was a firewall problem, i am however able to connect to 172.16.0.200 via telnet on ports 139, 88, 749.

Does anyone know of any interoperability problems with the win2k8 r2 AD? Do i need to alter any registry/auth settings on the AD?

Any help would be great - been stuck on this problem for the last two days...


Thanks
Tommy
