Spotlight searching no longer working - indexing and search disabled.

I've been searching the web and tried everything:

Server 10.5.8

In Server Admin - the attached drive is a SharePoint with Spotlight search on.

I've used mdutil to enable Spotlight.

I've checked permissions.

I can search the Boot Drive. I can't search the attached drive.

mdutil returns indexing and search disabled when used to turn it on.

very frustrating.

Anyone out there have a clue?

Thanks,

Mark
