Running IIS and Apache on the same server

You can not have two services offered on the same ip and port numbers.
On the same server, different services (IIS and Apache) need a unique IP/Port combination.

1) IIS might be binding to all ips on port 80. This has been the standard behavior of IIS since many years. So to run Apache with IIS, you first need to make sure IIS does not bind (i.e. listen) on all ips. The following article will help you disable IIS 6 from automatically binding to all ips on the Windows 2003 Server.

Before IIS6 (i.e IIS5), you simply had to set the metabase property "DisableSocketPooling" to true (and that was it).
For details on doing this see: Disable socket pooling on IIS5

FrontPage Guestbook, Board, Forms spam

The main raison for people spamming your FrontPage Guestbook, Forum/Board or forms is that the search engine Google, counts every "back link" (i.e. link pointing to these SPAM sites) as a positive vote. So if they can get a link to their site on your Guestbook, Google will interpret this as an "endorsement" of their site and give then additional "importance".

This spamming activity is especially common nowadays since they are thousands of automated scripts looking for FrontPage (or not, they will try to spam anything really...) guestbooks, boards, or forms to post SPAM links.
