Could not Setup : Web Service Identity

Today I am facing this problem on reporting service configuration.I have found 2 3 solution from below error . But Finally aspnet_regiis -i command works for me .

Error :

ReportServicesConfigUI.WMIProvider.WMIProviderException: An unknown error has occurred in the WMI Provider. Error Code 80070003 at WMIProvider.RSReportServerAdmin.SetWebServiceIdentity(String applicationPool)

Solution :

Run ASPNet_regiis -i

Restart your IIS

Path : C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis -i

If we wait until we’ve satisfied all the uncertainties,
it may be too late.
