How to find which server is having issue in Lync Group Expansion

Step 1 :

Click on Lync Icon in system Tray by pressing ctrl+shift  and then click on configuration information . From below screenshot you will get expansion url : https://lablncint01.bsci.com:443/groupexpansion/service.svc. Which is pool url .

To find which front end server is having issue replace pool name with server name.  https://lablncfep01.bsci.bossci.com/groupexpansion/service.svc . Since our lablncfep01 is working fine you will be able to browse as below.

When you replace with fep02 server. You will get below error as fep02 is having issue.

Step 02:

You can use shell to test same thing as below:

$credential = Get-Credential "bsci\guptaa10"

Test-CsGroupExpansion -TargetFqdn "lablncpool01.bsci.lab.com" -GroupEmailAddress "BSCMessagingOffshore@bsci.lab.com" -UserSipAddress "sip:akshit.behl@bsci.lab.com" -UserCredential $credential

You can replace –TargetFqdn with server name (labncfep01.bsci.lab.com).  Result of successful and failure attached in below txt file.

Step 03:

Modify host file in C:\Windows\System32\drivers\etc

Add entry lablncint01 with each front end server IP and see in Lync Client if you are able to expand distribution Group and identify faulty server.
