Question
Index dissappearing!!!
I have deployed a system in the field, in which 2 users (of about 1000) have reported that they keep getting an "index not found" error. I got their access DB in house, and sure enough, the primary key of one of my tables was missing, and I was attempting to do a seek on the index. The relationships that used that primary key are also gone.
Our system runs continuously (they do reboot every so often, but they also leave it up for days at a time). Every 3 days, during the middle of the night, I have a background process that runs, tells all the clients to shut their DB connection down, and then compacts, and signals the clients to restart. All of our inhouse testing, and the other 998 clients have no problem.
Both of the clients in question have a "network" setup, which means they have more than work station using the DB.... Basically, one workstation has the software and the DB on it, while the others have just the software, and point to the DB on th eother workstation.
Does anyone know of any reasons why an index would dissappear?

It sounds like there is a problem with the database that Access is not detecting. Are you sure there is no code that could drop the index?
All I can think of is creating a new database, import all objects except for the one with the corrupt index. Recreate the table in the new database and then import the data.
Bobby:
That's the solution I have them doing now. We have an EXE out in the field called "UpdateDatabase" which is called by our programs to check to see if the DB needs updating, and if it does, it updates the DB. I have the users that report the problem run this EXE with a /R switch, which tells my program to "update" the database anyway. Updating consists of copying all of the data from the main DB to a copy of a template I put out there...... I want to find a reason to why it is being removed. I'm not doing any DDL in the application at all, so there is nothing to remove the index.
