Yeah i got the remote viewing under control... With remote editing, I can do it with VBscript easy: Set objReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv") objReg.SetStringValue HKEY_LOCAL_MACHINE,strPointerKey,strPointerEntry,strPointerValue objReg.CreateKey HKEY_LOCAL_MACHINE,strMyKey surely .NET can do it. this is what i tried: RegistryKey LM = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine,WSID); RegistryKey inventoryKeys = LM.OpenSubKey("SOFTWARE\\CompanyName\\AppName"); inventoryKeys.SetValue("ValueName","Value"); and the error message is: Get REG values: System.UnauthorizedAccessException: Cannot write to the registry key. at Microsoft.Win32.RegistryKey.ValidateState(Boolean needWrite) at Microsoft.Win32.RegistryKey.SetValue(String name, Object value) at testReg.Class1.update() in c:\projects\testreg\class1.cs:line 48: 03/24/20 06 02:41:01 PM -- modified at 14:58 Friday 24th March, 2006
