I'm a bit confused...

Are you posting in ACCPAC Plus, or in Adagio?

If you are posting in Adagio, then you should make a backup just before posting the batches (File | Backup), so that you do not need to re-enter the batches if the posting fails.

You should not be running ACCPAC Plus at all under Windows XP SP2.

So, here is some information we need to try and help you track down what is happening:

• What version of Adagio Ledger are you running? (Help | About)
• What Novell client are you using? (Right Mouse | Properties | Client)
• Does it only happen on one workstation?
• If it fails over the network, does it also fail when the data is restored locally and posted locally?
• Are these new computers as well as new operating system?
