Exchange 2013 ecp iis error

After installing Exchange 2013 I got this “Server Error in ‘/ecp’ Application” when entering “Exchange Admin Center” web page.

“Could not load type ‘Microsoft.Exchange.Managment.Security.AdfsFederationAuthModule'”

Solution: Exchange 2013 did not install the “Windows Identity Foundation 3.5” automatically. So all there is to it, add this feature.

  

Enable Lync 2010 HD video

To enable HD Video:

Set-CsMediaConfiguration -Identity:Global -MaxVideoRateAllowed HD720p15m

(You can select one of 3 different resolutions : CIF250K, VGA600K (the default), and last the HD resolution Hd720p15M)

Enable-cstopology

Restart Lync frontend services.
