You have to use authentication type 9 (LOGON32_LOGON_NEW_CREDENTIALS) in
your call to LogonUser.
Something like this will do.

IntPtr admin_token;
// use LOGON32_LOGON_NEW_CREDENTIALS as LogonType
if (LogonUser("remDomainAccount", "domain", "pwd", 9, 0, out
admin_token) != 0)
{
WindowsIdentity wid_admin = new WindowsIdentity(admin_token);
WindowsImpersonationContext wic = null;
try
{
wic = wid_admin.Impersonate();
System.IO.File.Copy("source", \\\\server\\share\\dest, true);
}
finally
{
if (wic != null) wic.Undo();
}
}
else
{
int ret =
Console.WriteLine(Marshal.GetLastWin32Error().ToString());
}
