Thanks Mawells,

I've checked in the Home Directory tab on IIS, and it's set to 'A directory located on this computer', so no redirect there. I went to the directory specified, and modified the correct file - there's only 2 files there; it's a frames-based site (we're talking about a really old site!) so no difficulty making sure I'm editing the correct file.

I don't see any htaccess file... but that's only relevant on Linux / Apache, isn't it?

*Sigh!* What the heck is happening here??

I'll be back tomorrow. Ciao for now, and thanks for any input!

J.
