Unable to sign in using Communicator Web Access

Hi All,

Just been setting up Communicator Web Access.  When I try to sign in for the first time I get:

A problem occurred and the session was ended. Please sign in again. If the problem persists, contact your system administrator.(Error code: 0-0-18401-0-0)

I am using the same cert in the IIS bindings as with the configuration settings in the web access console.

Any ideas??

Last time we had this problem, it was a daft fix.

Reboot the front end....

Be aware that Microsoft does not support both CWA and Front end on the same server. you may have problems with IIS trying to serve both services. Can you separate them?
>> I've seen this twice, and both times it was that the CWA server wasn't trusting the front end server's cert.

famous words from mmcgille. see his post here http://social.microsoft.com/Forums/en-US/commmunicatorsetup/thread/8c5bf143-b41a-49e0-aa8c-021a3dccd193

hopefully that will help

I checked that post already, I have the cert assigned in the console as well as in IIS.  
The CWA site is on the same box as the communicator server.

any other ideas?

Im thinking the same thing, the problem may be because its on the same server...
