APPLIES TO
- Microsoft Exchange Server 5.5 Standard Edition
SYMPTOMS
When you log instances from the Oldest Message Queued performance counter for the MSExchangeMTA Connections performance object, you experience one or both of the following symptoms:
- If you use the Windows Performance tool in Microsoft Windows 2000 to log these instances, the Windows Performance tool reports very high values. Sometimes, these values may appear as several years.
- If you create a program to access the Performance Data Helper API of the Pdh.dll version 5.x redistributable DLL to log these instances, you receive error code 800007d6.
CAUSE
This problem occurs if the Message Transfer Agent (MTA) queue does not contain any messages. When an MTA queue contains a message, the MTA updates a counter with the current date and time stamp. A performance counter that you configure to be the Oldest Message Queued counter then shows that this message continues to age in the queue. You can determine how many seconds the message has been present in the queue. If the queue is empty, the performance counter still exists, but the MTA sets its value to zero. The Microsoft Windows NT Server 4.0 Performance Monitor tool correctly displayed this value as zero. However, the Windows Performance tool and Pdh.dll incorrectly display this value as the decimal value of the current sampling time stamp.
