Our Access 2007 database is constantly crashing on the network. The database has a 2007 shell linked to 2007 data tables on the same drive. Network has 1200 pcs and about 120 users - shell is about 120mb. Our repair involves copying a clean master shell - relinking to the data tables - creating a new shortcut and deploying the new shortcut across the network. This database was running last year OK in Access 2000 - in the summer the network was upgraded to Access 2007 and our problems started. At first the database was still in Access 2000 so we converted it to 2007 - still the same problem - next we rebuilt the database in 2007 by importing the objects from the 2000 database - stil we are having the same problem. Is it being caused by a rogue installation or 2 of Access 2007 ? When the database goes down it automatically creates a backup of the shell so we know when a problem has occurred. Any suggestions would be most welcome
