25 august 2009 14:05I'm running OCS 2007 R2 server Standard, CWA and edge server. Everything was working fine internally. Now if a client has a distibution list added to their contact list, Communicator ask for a password when it starts up and it doesn't take the regular AD password. If I click cancel, it loads and connects, but the Distribution group cannot be expanded and it gives this error:
Use of the distribution group service is restricted and requires specific permissions. Contact your system administrator to request the required permissions.
The strage thing is that if I log in using CWA the distribution group works properly. It seems to be some permission or authentication error, but I can't pinpoint. Any help would be appreciated.

Take a look at this blog article for more details, assuming that is your root cause: http://blogs.pointbridge.com/Blogs/schertz_jeff/Pages/Post.aspx?_ID=66

25 august 2009 16:22Thanks for the quick reply Jeff.
It's fixed now. I had to reinstall the Web Components on the FE. At one point I had CWA intstalled on the same box as the FE using 2 different IP's and certificates. It worked at that time, but I then decided to follow MS suggestions and move CWA on a separate server. Uninstalling CWA from the FE probably broke somenthing.
