USe ADSI. Go to WROX and do a search for ASP with ADSI. You can ping and do all sort of stuff on a network via VB or Vbscript,ASP. It's Pretty cool. Hope that helps.
I found an update version of the above code on www.freevbcode.com...it has facilities not only for pinging a host, but wrappers for "gethostbyname" and a few other nifty utilities that VB's Winsock doesn't have.
Things I've Said:
"Life's funny like that...elephants can wear frilly lace panties, and Dubya still looks like a monkey in a big chair"
"Take four goats and strap one to each foot of a llama. Presto, goat-powered llama!"
"You want to get me to work more, get me a Coke. No? Then deal with inferior garbage, I'm not coding another line and your clients can go to......thanks, I'd love a Coke right about now!"
