作为Windows服务托管时，远程WMI不起作用

Question

I am working on Remote WMI. I have done all DCOM settings, CIMV2 and WMI settings for particular User. When I run the application as console app, it works fine and fetches me the data. But when I host the same as Windows service, it is throwing exception as

Message:  Error Message: Access is denied. 
(Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) 
Inner Exception Message:  Stack Trace:    
at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)    
at System.Management.ManagementScope.InitializeGuts(Object o)    
at System.Management.ManagementScope.Initialize()    
at RemoteWMIRule.BackupServerRule..ctor()

Answer 1

Got Solved by adding Network and Network Service in DCOM Configurations. But still the problem persists in Windows Server 2008 R2 OS. Anything OS specific to be done???!!
