[Exchange 2013] Unable to start Exchange Toolbox

Hello all,

I have installed Exchange 2013 (CAS Role) on a Windows 2008 R2 server. All the requirements where passed.

After installing and the reboot, I am unable to start the Exchange Toolbox. It gives the following error:

Unhandled Exception in Managed Code Snap-in

FX:{714FA079-DC14-470f-851C-B7EAAA4177C1}

Exception type: System.Runtime.Serialization.SerializationException

Exception stack trace:

   at Microsoft.ManagementConsole.Internal.IMessageClient.ProcessRequest(Request request)
   at Microsoft.ManagementConsole.Executive.RequestStatus.BeginRequest(IMessageClient messageClient, RequestInfo requestInfo)
   at Microsoft.ManagementConsole.Executive.SnapInRequestOperation.ProcessRequest()
   at Microsoft.ManagementConsole.Executive.Operation.OnThreadTransfer(SimpleOperationCallback callback)

Any help is appreciated and with kind regards,

Willem-Jan
