 Correct workaround

1. Open Registry Editor (regedit).
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM. Export this registry key to a file before making any changes.
3. Locate the GracePeriod key and either delete or rename it. It may be necessary to take ownership of the key and/or modify its permissions first.
4. Reboot the RDSH server. You should now be able to successfully connect to it.
