Problem Executing Programs From ASP

I am trying to execute a ping command from ASP, and I am really not getting
anywhere. I wrote the following code based on what I found on the subject on
the Internet:

Dim sh, result
Set sh = CreateObject("WScript.Shell")
cmd = "ping 192.168.1.5 -n 1 -w 200"
result = sh.Run(cmd, 1, true)
Set sh = Nothing
Set result = Nothing

When I try loading the page containin this code, however, I get no response
from the web-server. And occasionally I get an error message saying that the
server could not handle the request due to too many users. Subsequent
requests to the server, also on other files, seems to end up in the HTTP
equivalent of a black hole, that is there is no response.

I am running WinXP (which is incidentally up-to-date with regard to Windows
Update) and IIS 5.1.
