Monitoring lost packets
let me explain my problem: One application Sharepoint server is loosing packets when i ping on it (20times OK, then packet loss, 10 times OK, one packet loss and so on …) and it causing Internet Exlorer crashes on clients who are working on this Sharepoint ("Page cannot be viewed" - right after that refresh displays page without problems).
Do you know any application which can be installed on host/client to find cause of these packet loss?
Just like tracking down loss on the Internet. Start with tracert/pathping, figure out at which hop the loss starts. From there, get some packet dumps.
