I've been attempting to use DirectoryServices to get the AppPoolIdentityType for an IIS App Pool on Windows 7. I wrote a simple C# console app to retrieve the app pool Id for the DefaultAppPool. DirectoryEntry dirPool = new DirectoryEntry("IIS://localhost/W3SVC/AppPools/DefaultAppPool"); PropertyCollection props = dirPool.Properties; string strAppPoolIdType = props["AppPoolIdentityType"].Value.ToString(); Console.WriteLine("AppPoolIdentityType: " + strAppPoolIdType); I can run this on Win2008 Server and Vista, no problem. However, when I run this app on Windows 7, I get the following exception: Unhandled Exception: System.Runtime.InteropServices.COMException (0x80070005): Access is denied. at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_AdsObject() at System.DirectoryServices.PropertyValueCollection.PopulateList() at System.DirectoryServices.PropertyValueCollection..ctor(DirectoryEntry entry, String propertyName) at System.DirectoryServices.PropertyCollection.get_Item(String propertyName) at GetAppPoolId.Program.Main(String[] args) I'm running this app from an admin account on both machines. Any ideas? Thanks, Wade

Hi Wade, Have you tried to disable the UAC? If not, you can try the following steps.1.Go to Start Menu -> Control Panel -> User Accounts -> User Account.2.Click on User Account Control settings-Choose Never Notify. I hope this can help you. John

UAC was the answer, I figured it out about 7PM last night. But I since I'm developing an app, I can't assume it's disabled. I figured out that I needed to setup the manifest to run the app as an admin automatically. UAC is one of the reasons Windows 7/Vista is user/developer hostile.
