This hotfix increases the highest possible value of the MinFreeConnections registry entry from 32 to 512. The MinFreeConnections value determines the free connection pool of the Server service.
On any Windows 2000-based computer that has version 5.0.2195.6930 or later of the Srvsvc.dll file installed, you can increase the MinFreeConnections value up to 512 and the MaxFreeConnections value up to 16384.
