When trying to create a new rule in the Group Policy Management Editor, after I have put the name in the Enter the object name in the select box of the Permissions page, I recieve the error Unhandled Exception in Managed Code Snap-in. This is the exact error I am recieving: Unhandled Exception in Managed Code Snap-in FX:{8A1A4AD2-7F9F-492c-9E1D-F725E3CBF2F0} Exception has been thrown by the target of an invocation. Exception Type: System.Reflection.TargetInvocationException Exception stack trace: Server stack trace: at Microsoft.ManagementConsole.Internal.SnapInMessagePumpProxy.OnThreadException(Object sender, ThreadExceptionEventArgs e) at System.Windows.Forms.Application.ThreadContext.OnThreadException(Exception t) at System.Windows.Forms.Control.WndProcException(Exception e) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Form.ShowDialog(IWin32Window owner) at Microsoft.ApplicationId.Framework.WizardForm.Start(IWin32Window parent) at Microsoft.Security.Srp.Ux.SrpUxRuleListView.CreateManualRule(RuleType ruleType) at Microsoft.ManagementConsole.View.DoAction(Int32 actionId, Boolean selectionDependent, Int32 selectionId, IRequestStatus requestStatus) at Microsoft.ManagementConsole.View.ProcessRequest(Request request) at Microsoft.ManagementConsole.ViewMessageClient.ProcessRequest(Request request) at System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.SyncProcessMessage(IMessage msg, Int32 methodPtr, Boolean fExecuteInContext) Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at Microsoft.ManagementConsole.Internal.IMessageClient.ProcessRequest(Request request) at Microsoft.ManagementConsole.Executive.RequestStatus.BeginRequest(IMessageClient messageClient, RequestInfo requestInfo) at Microsoft.ManagementConsole.Executive.SnapInRequestOperation.ProcessRequest() at Microsoft.ManagementConsole.Executive.Operation.OnThreadTransfer(SimpleOperationCallback callback) This happens after the Default Rules have already been created in the Executable Rules. I am connected to an ADDS, running Windows 7 Enterprise, and the Remote Server Administration Tools were downloaded from the server. Any help is greatly appreciated. *Edit* Since this post I have uninstalled/reinstalled RSAT and I am still getting the same error in the Create a New Rule Wizard after entering the Group Policy Creator Owners in the Permissions page. *Edit*
