Cannot open Exchange 2007 EMC or Powershell on Windows 2008x64.
Posted on 2014-02-21
Hi all. I'm having trouble with my Exchange 2007 EMC not opening. We haven't had to use it at this client for a while so I don't know when the problem started. But when we try to open Exchange EMC we get the MMC has detected an error in a snap-in and will unload it.
The further message is:
Exception has been thrown by the target of an invocation.
at Microsoft.ManagementConsole.Internal.SnapInMessagePumpProxy.OnThreadException(Object sender, ThreadExceptionEventArgs e)
at System.Windows.Forms.Application.ThreadContext.OnThreadException(Exception t)
at System.Windows.Forms.Control.WndProc(Message& m)
at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
I get no error messages in the event viewer when this happens. All services are running. Mail flow IS working.
But OWA doesn't launch either, even though IIS does. In the event viewer under system I see this:
A process serving application pool 'MSExchangeOWAAppPool' suffered a fatal communication error with the Windows Process Activation Service. The process id was '2848'. The data field contains the error number.
If I try to run the Powershell, the box just pops open and closed again, and I get the following in the event viewer:
.NET Runtime version 2.0.50727.4206 - Fatal Execution Engine Error (000007FEF95265EA) (80131506)
.NET 3.5 SP1 is installed.
No other corresponding messages to go with it.
I'm at a complete loss here. Any assistance would be greatly appreciated,
