FIX: No performance objects and no counters are listed in System Monitor when you enable the ODBC performance monitor counters on a computer that is running a x64-based version of Windows Server 2003

On a computer that is running a x64-based version of Windows Server 2003, you enable the Microsoft Open Database Connectivity (ODBC) performance monitor counters by using the ODBC Data Source Administrator tool. When you try to add counters in System Monitor (Perfmon.exe), no performance objects and no counters are listed in the Add Counters dialog box. Additionally, the following event is logged in the Application log:

Event Type: Warning
Event Source: Perflib
Event Id : 1016
Description:
The data buffer created for the "ODBC" service in the "C:\WINNT\system32\ODBC32.DLL" library is not aligned on an 8-byte boundary. This may cause problems for applications that are trying to read the performance data buffer. Contact the manufacturer of this library or service to have this problem corrected or to get a newer version of this library.
