Hi Syed thanks a lot for help, It fixed my problem Regards

Hi All, All of a sudden, one of DNS servers has an issue with wmiprvse.exe taking 99% of cpu. I have done some rerearch but nothing helped so far. I have downloaded the hotfix http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=1157 but I have not applied since I am not too sure if it is for Windows 2003 SP2 or not, Thanks and Regards

please perform a clean boot and monitor the server closely http://technetfaqs.wordpress.com/2009/05/18/how-to-clean-boot-in-windows-2008-server/http://www.virmansec.com/blogs/skhairuddin
