Terminal Services Licensing Service May Not Start and Event ID 43 May Be Logged

The Terminal Services Licensing service may not start on large databases and event ID 43 may be logged with the following description:

This behavior occurs because the Microsoft Jet database engine transactions can use a lot of memory on a large database (a database that is larger than 80 megabytes [MB] in size). Having a transaction hang (run for a long time before committing) or perform many modifications can cause Jet to consume the available version store.

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.

A new registry key is included in Windows Server 2003 to tune the default memory resources that are necessary for version store in Jet transactions. The version store keeps a list of changes that are made to the database since the latest transaction began. To tune memory resource that is necessary for version store in Jet:

1. Start Registry Editor (Regedt32.exe).
2. Locate and click the following registry key:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TermServLicensing\Parameters
3. On the Edit menu, click Add Value, and then add the following registry value:
   Value name: MaxVerPages
   Data type: REG_DWORD
   Radix: Decimal
   Value data: 1024
   Range is from Minimum 256 to a Maximum: 2048
4. Quit Registry Editor.
