my Operating system is Windows server 08 R2

FYI; From anonymous CLSID: 24FF4FDC-1D9F-4195-8C79-0DA39248FF48 refers to B292921D-AF50-400c-9B75-0C57A7F29BA1 in the registry which is the CLSID of the NAP Service agent. When I tried to edit the permissions in Component Services, I found that all the options were greyed out. I checked the services console and discovered that the NAP service was not running. The out-of-box configuration for Windows Server 2008 the Network Access Protection Agent start-mode is apparently "manual". Once I changed the start mode for that service and then started the service DCOM error was corrected, I have not seen an error since. (the two I just looked at use the Network Service account to start that service) Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]
