Time-taken Log Field Incorrect When KeepAlive Is Enabled

• Microsoft Internet Information Server version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

The Internet Information Server (IIS) log-file format contains a parameter for processing time. This field is the total amount of processing time that is spent on the server for a particular DLL. This internal timer starts on Packet 1 and ends on the last Acknowledgement received from the client indicating that that the processing has been completed on the server. However, the logged time is not correct if KeepAlive is enabled for the connection between the IIS computer and the Internet browser.

CAUSE

The counter that measures time is not reset for KeepAlive connections.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:
