I recently ran across a small problem while trying to open the Exchange 2010 Management Console. I received an initialization failure error message.
The full error message is below: “The attempt to connect to http://server/Powershell user ‘Kerberos’ authentication failed: Connecting to remote server failed with the following error message: The WS-Management service cannot process the request. The system load quota of 1000 requests per 2 seconds has been exceeded. Send future requests at a slower rate or raise the quota for this user. The next request from this user will not be approved for at least xx milliseconds.”
To resolve the problem, I opened a command prompt and ran iisreset.
Below are a couple of good links on Technet regarding EMC issues.
