Table name %.*s not found; check Sysobjects.
This error is usually caused by some form of corruption in the database. This often happens when a table is being dropped and a serious error occurs that causes the drop to fail.
Running dbcc checkdb, dbcc checkalloc, and dbcc checkcatalog can indicate other problems in the database. Restore your database from backup or contact your primary support provider for assistance.
You may also be able to use bcp to copy out other tables. But since this problem is often caused by other problems in the database, problems can occur when you copy out other tables.
