w3wp.exe high cpu utilization causes exchange 2010 to stop functioning
Posted on 2011-04-28
Since upgrading one of our Exchange 2003 servers to Exchange 2010, the w3wp.exe IIS processes regularly consumes 100% utilization every couple of days or so, which then stops exchange 2010 functioning. Checking the event viewer logs also shows the server lost touch with our domain controllers when this situation arises.
Since the only way we can temporarily rectify this matter is to restart the server - our Exchange 2003 works fine communicating to the same domain controllers and there is no problems with the network adapter card on the exchange 2010 server- can you please inform me how to rectify this matter?
