Hi Guys,

first up, sorry if this is the wrong newsgroup, but I looked the most
appropriate that I could find.

And yeah, I hear that Index Server isn't really supported by MS anymore...
So I'm hoping the community can help me out.

I've got a classic ASP app that uses Index Server/Indexing Services, to
crawl filesystem based content (mostly PDFs, but also the odd
Excel/Word/Powerpoint) and it's been running happy as larry on an old NT4.0
box(!) for ages. I've been porting it over to a Server 2003 R2/SP2 box and
having lots of fun on the way.

Note: the NT4.0 box had Office2000 installed, while the 2003 box has

The problem I've struck is that various XLS files want to recalculate at
certain times (usually on file open, given that they're from an older version
of Excel) and this seems to be getting in the way of the indexer. Using
Sysinternals Handles, I can see that cidaemon.exe is holding open the XLS
file, which in turn means that my ASP app can't open the file (just pulling
the title out using GetObject()).

In the past we've run various macro's over XLS files to replace all the
calculations with static values, but that's not always desireable.

Anyone have any ideas on how I can stop cidaemon from holding the file open?

Note: marking the file as read-only, kinda helps, as it forces my ASP app to
open it in read-only, which is fine and sucessful. But the indexer still as
the file open (effectively stopping any admins from renaming, deleting or
moving the file).
