I still cant figure this out... when i make admin modifications after i post changes, it sometimes re-directs to default.asp which is ok, and other times it re-directs to index.asp and this time i get an error 404,
Within IIS there are setting to tell it what default page should be loaded when someone just types a URL ending in / e.g www.myforum.com/forum/ Becuase the user hasn't specified a page to be loaded, the IIS server goes through a list of defaults loaded. Normally with IIS 2 default page names are loaded. One is index.asp the other index.htm
What your seeing is some snitz pages when redirecting, specifically telling it what page to load .. ie www.myforum.com/forum/default.asp (these are the ones that are working) and others specifing just www.myforum.com/forum/ (the ones that arent working).
Email your webhost and simply ask them to change the default homepage settings to include 'default.asp' should fix your problems.
