If your network is Novell, and Client32 on your workstation is either version 4.83 or version 4.90, you will need to go to the Novell website and download a service pack. There are known issues with the unpatched versions of these network clients, and will cause problems in programs such as Adagio.
This isn't necessarily the cause of your posting issues, but certainly the first thing to check.
You should also determine if File Caching or Opportunistic Locking is enabled on the Novell Client; it should not be for Adagio to work successfully. Often when a new update for Novell Client is installed, the default choice for the above settings is On.
It may be useful to know an example of the reported data integrity errors, such as an account out of balance or an incorrect batch total. Usually the Rebuild function will not attempt to rebalance accounts, which would be why the Rebuild did not change the error count.
