For the past week I've tried everything I can think of to get one user's Lync/S4B client connected. It just says connecting and eventually times out. Up until last week, his Lync/S4B has worked fine for years. Fixes so far:
- Deleted sign-in info on lync desktop client.
- Deleted lync cache (sip_emailaddress) under %LOCALAPPDATA%\Microsoft\Office\15.0\Lync
- Deleted the RSA key under %USERPROFILE%\AppData\Roaming\Microsoft\Crypto\RSA
- Checked the Certmgr.msc if there are existing certificate comming from Communications Server. No certificates found.
- Deleted the files under %USERPROFILE%\AppData\Local\Microsoft\Office\15.0\Lync\Tracing but retain the folders.
- Performed ipconfig /flushdns
- Restarted the computer.
- Uninstall/reinstall Lync/S4B
- Removed/re-added user in Lync Control Panel.
The user can ping the server just fine. I attempted to sign in on his client but I received the same issue he gets.
Edit: How can I manually get that cert if it is not being issue? Every other person in my organization has one and is connected to Lync/S4B fine.- Edited by MicrosoftUser5 Thursday, September 03, 2015 6:24 PM
