It seems that one of our remote gateways do not allow remote users to establish a connection to their MS Communicator Client.
Lets call this gateway 'West'
"You have been signed out of Communications Service because that service has been temporarily shit down. Please try again later."
Now if the users connect to another gateway called 'East' they can connect just fine to MS Communicator.
We have a another installation of LCS 2005 SP1 within another domain. When I test going through the 'West' gateway I receive the following message:
"The was a problem verifying the certificate from the server. Please contact your system administrator"
So is it something with the 'West' gateway or the LCS servers not allowing access when authenticated through the 'West' gateway?
