In our environment we have 6 Windows Server 2008 R2 servers, 4 application servers, one web server and one SQL server. A website is served on the web server that is used to monitor the status of the other servers. One of the items monitored is running services. To achieve this we use the ServiceController class found in System.ServiceProcess. After the upgrade from Windows 2003 to Windows Server 2008 R2 we began experiencing performance issues with our monitoring website. Page execution will often exceed two minutes causing a 404 error on the client side. I have narrowed down the culprit to be the running services query described above. After the initial execution lag, performance of the service query returns to normal for a brief time, approximately 15 to 20 minutes after which we get another incident of the performance problem and the cycle repeats. I have several questions: 1) Is ServiceController built on top of WMI? If so, is WMI still experiencing performance problems as described here. 2) Is there an alternative method for querying service status on a computer within the domain (i.e. not the local computer)? 3) Could there be network environment variables I've not considered? (I'm a developer, not a network engineer)
