SYMPTOMS
In Microsoft Windows 2000, when you use the Ping command-line tool to test connectivity and round-trip time (RTT), you notice that the times are not accurate to the millisecond.



CAUSE
This problem occurs because timers in Windows 2000 measure time based on the Internet Control Message Protocol (ICMP). The ICMP time measurement is in 10 millisecond increments.



RESOLUTION
The hotfix that is provided in this package lets the Ping command-line tool measure RTT in one millisecond increments.
