I am running Exchange 5.5 SP4, Windows 2000 SP2, and the security Rollup SP1. Compaq DL 380 with all the Compaq Tools. Also running HP Openview to monitor things. I get the following messages repeatedly. Is there a way to stop them or get rid of them? Event Type: Warning Event Source: Perflib Event Category: None Event ID: 1016 Date: 3/28/2002 Time: 4:26:01 PM User: N/A Computer: Server Name Description: The data buffer created for the "MSExchangeDS" service in the "D:\EXCHSRVR\bin\perfdsa.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 Contact the manufacturer of this library or service to have this problem corrected or to get a newer version of this library. Data: 0000: c4 ea 13 00 b4 03 00 00 Äê..´...
