I just discovered a problem with the latest CU for Lync Server 2010.
Seems like this update ruins the web Components URL’s so that they no longer work. just installed the update in a custommer environment. After the update, online Meetings stopped working. Couldn’t figure out why, so I did som google’ing and quickly discovered other similar problems with previous CU’s(from October 2012).
I proceeded to unistall the update for “Microsoft Lync Server 2010, Web Components Server” and rebooted the FrontEnd server.
The URL’s are working again. Don’t know why this happens, any comments are greatly appreciated 🙂
