Hi Chris.. >From reading up on the SMB2 protocol it seems that this is implemented within Vista and greater MS clients, but I do not seem to be able to track support for SMB2 within SAMBA I see that there is a Samba4AD project but cannot find rpms for RHEL and am a bit cagey about putting a dev version onto a critical file server. And the Citrix (client) servers are 2003 SMBv1 anyway so that kind of kills that anyway. Thanks Jay On 22 June 2010 17:08, Christopher R.
