Denis:

I set up a batch with two 700 line invoices. It took less than one minute to post them. Granted no one else is on the network but 30 minutes is way to long no matter what else may be happening.

I suspect that Andrew's response this morning is likley the right answer.

I'm running Dell optiplex workstations and Dell PowerEdger server with a Gigibit switch. The server is running Windows 2003, Raid5 configuration and 4GB of RAM. Workstations are XP Pro with 2GB RAM. Network cards are all Gigibit as well.
