Receiving Multiple Instances of Event ID 2022

When you are using a computer running Windows, you may receive the following error message:

This behavior occurs because the Server service is unable to keep up with the demand for connections.

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.

To work around this issue, use the following steps:

1. Start Registry Editor (Regedt32.exe).
2. Locate and click the following registry key:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
3. On the Edit menu, click Add Value, and then add the following registry value:
   Value Name: MaxFreeConnections
   Data Type: REG_DWORD
   Value: Any Value Up to 100 (in decimal)
4. On the Edit menu, click Add Value, and then add the following registry value:
   Value Name: MinFreeConnections
   Data Type: REG_DWORD
   Value: Any Value Up to 32 (in decimal)
5. Quit Registry Editor.

NOTE: You must restart the computer for the changes to take effect.

A special resource task in the Windows service uses the MinFreeConnections and MaxFreeConnections value settings to preallocate connection objects. Under certain conditions, the demand for preallocated connection objects may exceed the default number configured in the MinFreeConnections and MaxFreeConnections value settings.

However, you may also receive the "Event 2022" error message due to certain system problems (for example, if the computer stops responding). You should correct any system problems before you consider changing the MinFreeConnections and MaxFreeConnections value settings.
