To start off with a confession, I am not a server admin - just a developer tasked with getting to the root of a problem. Please be gentle!
I have an intranet ASP.NET website running in IIS on a virtual machine. The website is not accessed very often (the last IIS log file was modified nearly six months ago). Both the IP address and Host header value are now failing to return the website, and the IIS log still doesn't show any more recent activity.
The virtual machine was moved to a different physical location a few months ago, and the IP address for it has changed. Could this be what has broken access to the site? What else should I be checking to solve this?
I don't have totally unrestricted access to the building's network settings, structures, etc. I would be grateful for any advice, even if I can't use it myself it'll improve my knowledge of what's going on behind the scenes!
