Resolution

This happens if the Terminal Services service registry values are missing or has incorrect entries. To resolve the problem, download the file termsvcfix.zip available below. Unzip and run the utility. After running the utility, restart Windows and check if the Terminal Services service starts correctly. Note that this utility modifies the service related registry keys, and so requires administrator credentials to run correctly.
