How to change the registry value of remote system using C#
Hai every one I am developing an windows application in which i have to block the removable storage devices such as pendrives.I found that its possible by changing the registry value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor,start value to 4.But the problem is I have to block it on remote systems too.Can any one suggest me how to change the value of registry of remote system using c# with a code or sites where i can i find the code for this.
The .net way is to use Microsoft.Win32.RegistryKey.OpenRemoteBaseKey. An alternative would be to use WMI. There are lots of examples on Google for reading values; replacing GetStringValue with SetStringValue (or SetDWORDValue, etc.) should do what you want.
You probably want to take a look at the Remote Registry Service and make an RPC call. MSDN description: http://msdn.microsoft.com/en-us/library/aa940121(WinEmbedded.5).aspx MSDN example using RegistryKey.OpenRemoteBaseKey: http://msdn.microsoft.com/en-us/library/8zha3xws.aspx
You need to have Remote Registry service running on remote machine. Then you can use WMI to connect the registry. Here is a code sample script from this site: Dim strComputer Dim strUserName Dim strPassword Dim objLocator Dim objService Dim objRegistry strComputer = "somesys" strUserName = "somename" strPassword = "somepw" Set objLocator = CreateObject("WbemScripting.SWbemLocator") Set objService = objLocator.ConnectServer( strComputer, _ "Root\Default", strUserName, strPassword ) objService.Security_.impersonationlevel = 3 Set objRegistry = objService.Get( "StdRegProv" ) 'Do something here like retrieving or setting values. Set objRegistry = Nothing Set objLocator = Nothing Set objService = Nothing you can get many valuable results by googling for "using WMI to modify remote registry"
