Can you check the following1. Check the following registry key on the GC and make sure that it is in place: HKLM\System\CurrentControlSet\Services\NTDS\Parameters Type: REG_MULTI_SZ Name: NSPI interface protocol sequences Value: ncacn_http:6004 2. GC has to be rebooted once this key is punched in.Also have a look into thishttp://www.petri.co.il/forums/archive/index.php/t-34969.htmlRaj

Hi,This issue can be caused by several factors, such as the validport on the CAS or the GC is not listening on port 6004.To troubleshoot this issue, please refer to the below article:http://messagexchange.blogspot.com/2008/12/outlook-anywhere-failing-rpc-end-points.htmlAdditionally, to better understand how does Outlook Anywhere work, another useful article is as below:http://msexchangeteam.com/archive/2008/06/20/449053.aspxThanksAllen
