Fix: Error 500 when loading Shell or ECP on Exchange 2013 SP1

After installing Exchange 2013 with SP1 you might notice that when you open the Management Shell, you will get a bunch of errors with mainly the error 500: Internal Server Error. This can also be seen when you try to access the ECP or OWA on the server in question. This issue is only on Exchange 2013 with SP1 and with Client Access role installed.

The culprit can be the following three:

#1 Time synchronization

On the Primary Domain Controller (PDC) do the below

net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:0.pool.ntp.org
w32tm /config /reliable:yes
net start w32time

On the other DCs and servers do the following

net stop w32time
w32tm /config /syncfromflags:domhier /reliable:no /update
net start w32time


#2 Kerberos issues

Do the following on the effected servers to re-create the Powershell virtual directory.

Get-PowerShellVirtualDirectory -Server | Remove-PowerShellVirtualDirectory
New-PowerShellVirtualDirectory -Server -Name PowerShell
Get-PowerShellVirtualDirectory -Server | Set-PowerShellVirtualDirectory -BasicAuthentication:$false
IISReset

After virtual directory re-creation I have checked its modules in IIS and made sure, that Kerberos module is native and the path to its DLL is correct.

#3 WinRM Extensions

The feature might be missing, do the below to add the feature

Get-WindowsFeature *IIS* #to check if it is installed
Add-WindowsFeature Winrm-IIS-Ext # to install
