Dr Watson Starting TS License Service with Error 3221487623

In the Event Log, you observe that Terminal Server licensing fails to start with the following errors:

There are three probable causes for this issue:

• Incorrect versions of ODBC components.
• Incorrect ODBC System DSN entries.
• Corrupted Hydra MDB.

To resolve this issue, you need to check several items in the ODBC Data Source Administrator.


WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1. Check the ODBC versions: note that the version of ODBC that shipped with Windows Terminal Server is older than the version that is in MDAC 2.0, but carries a newer date. The minimum version supported on Terminal Server can be any of the following:
   
   
   • From the default Terminal Server version 3.51.102900, dated 5/31/98.
   • From MDAC2.0 version 3.51.171300, dated 5/14/98.
   • From later versions.
   
   If any of the components are NOT the same version or ANY of the 32-bit components are not the same version, the entire ODBC must be completely reinstalled.
   
   For additional information about installing ODBC, please see the following article(s) in the Microsoft Knowledge Base:
   216149  (http://support.microsoft.com/kb/216149/EN-US/ ) How to Install ODBC or MDAC on Terminal Server
2. Check the following entries in the System DSN for Hydra License by opening the Configure box. The correct entry is "Hydra License" with no trailing spaces or carriage returns. Ensure that the database entry points to the correct location of the Hydra.mdb. System Database is none. Open Set Advanced Options and check the Default Authorization for the entry "sa" (lowercase, short for system authority).
   
   If any of this information is different, the best thing is NOT to modify this entry but to create a new entry. Start from the System DSN panel and click ADD. Select the driver for Microsoft Access, click finish, and then enter all of the information outlined above.
3. To resolve a corrupted Hydra MDB, please see the following article(s) in the Microsoft Knowledge Base:

4. Change the entries for the ODBC driver and DBQ:
   
   
   1. Locate the following keys in the registry:
      HKLM\Software\ODBC\ODBC.ini\Hydra License\DBQ
      HKLM\Software\ODBC\ODBC.ini\Hydra License\Driver
   2. Change the drive letters in each entry.
   3. Restart the computer.
