Impersonate user for file read/write on network share

I am having trouble getting the logon user function to work. I am attempting to access a share on a network computer.  The account I am using is a local account on the manchine - Not a domain account.  If I use the logon_new_credentials, the login succeeds but the createdirectory returns bad user/password



IntPtr lnToken;
       
     //   LOGON32_LOGON_NEW_CREDENTIALS - Using this the logon succeeds but the create directory still returns bad username/ passord
        int TResult = LogonUser(@"remotecomputer\adminuser", "RemoteComputer", "password", LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, out lnToken);
        Win32Exception e = new Win32Exception();
        string x =e.Message;
        if ( TResult > 0 )
            {
 
           ImpersonateLoggedOnUser(lnToken);
           using( WindowsIdentity.Impersonate(lnToken))
           {

               Directory.CreateDirectory("\\\\remotecomputer\\ShareedFolder\\Test");

           }
           
                  StringBuilder sb = new StringBuilder(80,80);
                  RevertToSelf();
                  CloseHandle(lnToken);
            }
            else
            {
                  
            }


            return;
