Hi There I have 2 domains that I manage, they have a trust and network connectivity between them. One has an UAG Server which is used for Direct Access to Domain A, we would like Domain B users to be able to use this server to connect through to Domain B. Is this possible without Forefront?. At present Domain B users have a contact on Domain A which has the ObjectSID (from domain B) in the msRTCSIP-OriginatorSid field (on Domain A) to allow Lync connectivity which is working well - is there a similar setup for UAG? Thanks

Hello, for networking you should consider using http://social.technet.microsoft.com/Forums/en/winserverNIS/threads and for Forefront UAG http://social.technet.microsoft.com/Forums/en-US/forefrontedgeiag But for trust connectivity and authentication you have the need of connection between the DCs. At least this ports MUST be open http://support.microsoft.com/kb/179442/Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.
