Hi All 1) I have installed AD-RMS role in windows server 2008 R2 with errors. Without tweaking much i decided to uninstall and deleted the IIS hosted website(so cannot do any Edit binding for Http) and deleted the newly created user for RMS server. 2) I have gone through many postings regarding this. I just want to remove RMS role from the machine . 3) Now If i want to remove the RMS role completly, how do i procedd this. If try to remove i got the following error. Uninstall-ADRMS : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.Collections.CollectionBase.System.Collections.IList.get_Item(Int32 index) at System.DirectoryServices.PropertyValueCollection.get_Item(Int32 index) at Microsoft.RightsManagementServices.Configuration.ProvisionHelper.GetPort(String strTargetComputer, String strIIsS ervice, String strSiteindex, Boolean fSSL) at Microsoft.RightsManagementServices.Configuration.ProvUtils.GetWebsites(String strTargetComputerName, String strII sWebService) at Microsoft.RightsManagementServices.Configuration.ProvUtils.IsProvisioned() at Microsoft.RightsManagementServices.Configuration.ProvisioningBase.Unprovision() at Microsoft.RightsManagementServices.Configuration.ProvisionerBase.Unprovision() at Microsoft.RightsManagementServices.Configuration.CmdLineHandler.Run() At line:1 char:16 + Uninstall-ADRMS <<<< + CategoryInfo : InvalidResult: (:) [Uninstall-ADRMS], Exception + FullyQualifiedErrorId : Unprovisioning,Microsoft.RightsManagementServices.Configuration.UninstallADRMS
