I was able to successfully install the exchange service pack 1 yesterday after some attempts but now after everything is running, I tried to expand the certificate option in EMC and saw the following error message pop out
--------------------------------------------------------Microsoft Exchange Warning
--------------------------------------------------------
Warnings
Get-ExchangeCertificate -Server 'Name of Server'
Completed
Warning:
An unexpected error has occurred and a Watson dump is being generated: Could not load type 'ADObjectOutOfScopeString' from assembly 'Microsoft.Exchange.Configuration.ObjectModel, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
--------------------------------------------------------
OK
--------------------------------------------------------
Does anyone have any idea on how to solve this?
