In a Microsoft Exchange Server 2010 environment, you encounter failures when you run the Test-EcpConnectivity cmdlet to test Exchange Control Panel connectivity to a server that is running Exchange Server 2010 and has the Client Access server role installed. Also, if the Exchange Server 2010 environment is monitored by Microsoft System Center Operations Manager (SCOM) 2007 R2, the administrator receives the following alerts every five minutes because this cmdlet is executed:
Source: MSExchange Monitoring ECPConnectivity External
Message: One or more of the ECP connectivity tests failed.
Target: Client Access Server|Site
Error: The server didn't return a user context cookie.
This issue occurs because the Test-EcpConnectivity cmdlet uses an invalid user-agent string in HTTP requests when it tries to connect to the Exchange Server 2010 Client Access server.
To resolve this issue, install the following update rollup:
2661854 Description of Update Rollup 2 for Exchange Server 2010 Service Pack 2
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
