Database indexes are very similar to the page numbers of an encyclopedia or the keyword index used at the back of an encyclopedia. They sort the records present in a database table and help to increase the performance of the database by enabling faster 'SELECT' queries. But, these indexes may get corrupt due to several reasons, such as improper shutdown, human errors, system crashes, abrupt closing of the application etc. This could make your database corrupt and may require you to go for database recovery. Corrupt database indexes may lead to an improper functioning of your database system. You may also see a few incorrect results in the output window for some queries. It may also prevent you from accessing the valuable data stored in your database file. To overcome this situation, you need to perform SQL repair of your corrupt database through a third party utility.
Sometimes, you might have seen the following error message in the MS SQL Server 2000 error log after trying to modify a database table:
"Could not find the index entry for RID '160314a879010000' in index page (1:428288), index ID 3, database 'DATABASENAME'"
Cause:
This error has occurred because of an index corruption in the database file. It is a non-clustered index as the index ID is greater than 1.
This may render your precious data stored in the database inaccessible. At this stage, you can restore your corrupt database through a backup. If you don't have a backup, you should try performing
SQL Database Recovery through below mentioned resolution steps.

These steps might help you solve the problem-
Try rebuilding all the indexes created on the database.
