Access is denied message connecting to remote server using impersonation

[Tony]

my remote endpoints are all win 7. i'm running the following code:
string[] servers =
ConfigurationManager.AppSettings["ServerNames"].Split(',');
string serverUser =
ConfigurationManager.AppSettings["UserName"];
string serverPassword =
ConfigurationManager.AppSettings["Password"];
MakeDataTable();
foreach (string server in servers)
{
ITerminalServicesManager mgr = new
TerminalServicesManager();
IntPtr token;
if (!NativeMethods.LogonUser(serverUser, server,
serverPassword, NativeMethods.LogonType.NewCredentials,
NativeMethods.LogonProvider.Default, out token))
{
throw new Win32Exception();
}
try
{
IntPtr tokenDuplicate;

if (!NativeMethods.DuplicateToken(token,
NativeMethods.SecurityImpersonationLevel.Impersonation, out
tokenDuplicate))
{
throw new Win32Exception();
}

try
{
using (WindowsImpersonationContext
impersonationContext = new
WindowsIdentity(tokenDuplicate).Impersonate())
{
using (ITerminalServer serverInstance =
mgr.GetRemoteServer(server))
{
try
{
serverInstance.Open();
IList<ITerminalServicesSession>
sessions = serverInstance.GetSessions();
}
catch (Exception exp)
{
string msg = exp.Message;
string trace = exp.StackTrace;
}
...
when i invoke serverInstance.GetProcesses or any other method on the
serverInstance object, i get an exception. The user i'm connecting as
is an administrator user on the windows 7 remote server. i'm pulling
my hair trying to figure this out. here's the exception:
"Access is denied"

Tony,

See this thread. Have you set AllowRemoteRPC appropriately on the Windows 7 machines?
