We never really got to the bottom of it but we did the following to resolve it.....
Upgrade to W2000 and ban W98 from using protel. Specify at least 1G RAM Forbid multiple access of schematics, though we do allow simultanious PCB / SCH use - reluctantly. Regularly backup to multiple destinations and keep a 30 deep history of backups, disk space is plentiful. Regularly compress the database If possible store the .DDB on a local machine rather than a server I think the main cause was W98 and low resources caused by background tasks. We've not had a corruption in a very long time. Protels' 'network awairness' is crap, considering its their selling point its got to be taken with a pinch of salt. As I said previously, multiple users of the same .ddb can cause loss of data as file / record locking is not done right, its optional and manual. It should work more like CVS whereby changes can be merged and controlled. Also when working on a network copy we get much more frequent 'Protel has caused a...' messages. There is somthing really screwy with it. To give them grace, its probably not Protel's fault, they are relying of sombody elses software (JET) to work with multiple users.

Jason, There is a Protel KB item on this - KB Item 1985. I have been caught by this in the past as well. But since Protel have the KB item I will not add it to the database (unless enough people request it). What I am trying to achieve with the database is some visibility and memory of problems that have not made it to the Protel KB or have persisted so long that they should have been fixed by now. Jason - did you get any further in determining why you had a many instances of DDB corruption while operating over the network? This info and any warnings you can give would make a good bug database entry( or entries). This is something that Protel KB is not very forthcoming on and the marketing bumpf makes claims to network operations.
