Reporing Service and deploy permission

Dear all,

I use Window Vista+ Sql server 2005 with SP 2

When I deploy the report in Report designer, the following error message display

The permissions granted to user 'winVista\admin' are insufficient for performing this operation.

The user "admin" is a admininstor and I assign the following group to it

(1) administors

(2)WINVISTA\SQLServer2005ReportingServicesWebServiceUser$WINVISTA$MSSQLSERVER

(3)WINVISTA\SQLServer2005ReportServerUser$WINVISTA$MSSQLSERVER

Which and Where I must assign the permissions to this account?

thanks you

If you connect to Reporting Services in Sql Server Management Studio, right click on the servername and select the properties of the server. Then select the permissions page. What's in there?
