Hello all...first time member...

I testing BES 4.1 in a test environment. While mailflow seems to be working fine, LCS and Internet are not. When I initially installed BES 4.1, everything seemed to work fine. Then, we wanted to simulate an upgrade from 4.0 to 4.1 so I uninstalled 4.1 and also deleted all of the registry keys as noted in the Install guide. I installed 4.0, upgraded to the SP, then installed BES 4.1. Now, I cant get LCS to work. I continue to get the following error message:

"Unable to contact server. Please contact your IT Administrator if the problem persists".

My Collaboration Service settings are:
Status: Running
Service type: LCS
Default Domain Name:
Host: <servername>.domain.com
Port: 5060
Transport protocol: TCP

Does anyone have any ideas of why this is failing? Thanks.

Test to make sure you can make an LCS connection from the BES to the LCS server. Load the Office Communicator 2005 client onto the BES and connect. Let me know how it goes, and I will help if I can. i am working on our BES/LCS today also. Just upgraded from 4.0 to 4.1 SP1 with 1100 users.

I should have been more specific in that we're trying to make this work in a failover environment. One thing we found is that the MSMQ service needs to be stopped on the passive node. The other problem we're seeing is that when we fail over, in the Server Config utility we notice that on the MDS Advanced Tab, the default server is "None". We have to manually point it to the BES.

Wierd.

which version of LCS you are running 2003 or 2005? and did u applied BES 4.1.2 or just 4.1.1 ???
