How do you detect packet-loss on Windows Server 2003?

Question

Is there any way to detect packet loss with the help of performance counters or am I better of using a 3rd-party tool? What tools would you recommend?

Answer 1

netstat -s will show you the total count of retransmissions. Wireshark can capture traffic and got an "expert info" (under Analyze) that will tell you about obious network related errors.
