I have a Windows 2003 Web ED server. IIS has a Virtual Directory that has a sales application in it. the program can me accessed thru IP/salesprogram. the actual files are in C:\program files\Company\salesprogram. I have a site maindomain.com hosted by a provider. I made a subdomain thru them salesprogram.maindomain.com. Everything is good to there. They told me to make a PTR to the server. So I put (A) 192.16.25.10 (of server) salesprogram.maindomain.com WAN IP. Also NS salesprogram.maindomain.com WAN, and reverse lookup 192.16.25.xxx with a PTR 192.16.25.10 salesprogram.maindomain.com. Know the problem is I need the Virtual Directory to be linked to the salesprogram.maindomain.com. I dont know tomuch about IIS. The Virtual Directory is a child of Default, that has nothing in it. Tried to link in Website tab, next to the IP Address Advance button, but in the Virtual Directory it does not have that option. Im boggoled. The provider knows nothing about FQDN, its kinda scary if Im there only customer that has thought of this idea.
