Today I had an issue appear when opening the Exchange Management Console on a 2010 server. The error message was :
Initialization Failed. The following error occurred while attempting to connect to the specified Exchange server 'Server name'. The attempt to connect to 'Server Name' using "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 system quota. The next request from this user will not be approved for at least value milliseconds.
To resolve this issue carry out an iisreset on the server.
