Run process Remotely

Hi, I developed an application (App1.exe) that has to be run from a main Server (Server1), so, all you have to do is run the following command "\\Server1\myDir\App1.exe". There is no problem with that, except that the App1.exe has to use some functions to access the Registry of the Client where is running the application, besides some files that are also at the Client Machine. If I have the App1.exe copied at my machine, of course there is no problem, but if I run it from the Server1, it throws a Security Exception as follows: "System.Security.SecurityException" related to "System.Security.Permissions.RegistryPermission" How do I tell to the application (programatically of course) that run with the rights of the user whom started it remotely? This in order to access the local registry and the local files. Thaks for any help.

Hi, This is from VStudio help: using System; using System.Runtime.InteropServices; using System.Security.Principal; using System.Security.Permissions; [assembly:SecurityPermissionAttribute(SecurityAction.RequestMinimum, UnmanagedCode=true)] public class Class1 { [DllImport("C:\\WINNT\\System32\\advapi32.dll")] public static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, out int phToken); [DllImport("C:\\WINNT\\System32\\Kernel32.dll")] public static extern int GetLastError(); public static void Main(string[] args) { // The Windows NT user token. int token1; // Get the user token for the specified user, machine, and password using the unmanaged LogonUser method. bool loggedOn = LogonUser( // User name.

"coffee", // Logon type = LOGON32_LOGON_NETWORK_CLEARTEXT. 3, // Logon provider = LOGON32_PROVIDER_DEFAULT. 0, // The user token for the specified user is returned here. out token1); Console.WriteLine("LogonUser called"); // Call GetLastError to try to determine why logon failed if it did not succeed. int ret = GetLastError(); Console.WriteLine("LogonUser Success?

WindowsImpersonationContext mWIC = mWI2.Impersonate(); Console.WriteLine("\n\nAfter impersonation:\n"); WindowsIdentity mWI3 = WindowsIdentity.GetCurrent(); Console.WriteLine(mWI3.Name); Console.WriteLine(mWI3.Token); // Revert to previous identity. mWIC.Undo(); Console.WriteLine("\n\nAfter impersonation is reverted:\n"); WindowsIdentity mWI4 = WindowsIdentity.GetCurrent(); Console.WriteLine(mWI4.Name); Console.WriteLine(mWI4.Token); } }
