I have a MOSS Enterprise site collection whose URL was recently changed (via
AAM). Now I get a 404 whenever I click on any library in that SC. The
straight lists, however, show up with their views intact. A look at the
virtual file system in Designer shows that the view files are all there, of
course; furthermore, when I go directly to another view in a library, the
page renders correctly.

Naturally I suspected a missing or broken linked file. On a whim, I fired
up WinMerge and opened AllItems.aspx next to another view in the same list.
According to WinMerge, the files are identical, which seems like a stretch
-- but I double-checked and I am indeed looking at two different files.

Beyond that, I looked for evidence of the true culprit in the IIS logs, but
the only 404s in there are (a) the default view for each library that I've
tried to hit, and (b) a bunch of (presumably browser-generated) requests for
favicon.ico.

Any thoughts about where I should look next? I don't see anything notable
in Event Viewer.
