The attempt to connect to http://yourserver.domain.local/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 X milliseconds.
If you see the above message when trying to open the Exchange Console you will be probably asking yourself WTF, as I was a couple of days ago, mainly because the error message says nothing about how to solve it, Events are all normal and your Exchange Server is performing ok apart from the console not opening. After wandering about the issue I found that a simple iisreset (do not forget about running the command in an elevated Command Prompt or PowerShell session) will do the trick, I am still researching about how this error is generated and why resetting the IIS service works to fix it, in the mean time this is the workaround.
