W2K3 / IIS6
Problem seems to have started over the weekend. There are about 8 sites in total on the server. Sites w/o SSL or accessed via http:// do not work remotely at all - but can be browsed from within IIS Manager on the server.
IIS logs indicate status 200 on the index pages, but no other content is served remotely. Directly linking to a couple 3mb ZIP files available for download lets them go to about 98% and then the download breaks.
I deleted one site from IIS Manager and re-added it changed the error from a content not supported to one that loads the text of the site, but no CSS or images - just the a portion text in the HTML document (it starts to display from a random position in a style tag in the head of the document)
No changes were made to the server and I've been at this for an hour now trying to figure out what's going on. At this point I am completely baffled!
