>I developed a Web site a couple of months ago using Web Connection for a client that is a couple of hours drive from my office. Can anyone recommend a good way for me to be able to make sure their web site is running properly? The web site is actually running on an intranet so I cannot access it through my ISP to see if it is up. I do have access to their network using dial-up networking.
