SYMPTOMS

When you use Windows NT Performance Monitor to check the performance of the Microsoft Mobile Information Server or the Microsoft SharePoint Portal Server or Microsoft Exchange Server 5.5, the following event may be logged in Microsoft Event Viewer for each Performance Monitor session:

Event ID: 1016
Source: Perflib
Type: Warning
The data buffer created for the "MSMQ" service in the "C:\Winnt\System32\MQPERF.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 Contact the manufacturer of this library or service to have this problem corrected or to get a newer version of this library.

WORKAROUND

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, add the following registry key that prevents Performance Monitor from testing for data buffer alignment errors:

Start Registry Editor (Regedt32.exe).
Locate and click the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Perflib
On the Edit menu, click Add Value, and then add the following value:
Value Name: Configuration Flags
Data type: REGDWORD

Quit Registry Editor.
