Ping failure above 23,672 bytes AND/OR QB H202 error

Medium Priority
Last Modified: 2020-03-20
I'm getting Quickbooks error H202 multiple times per day when using multi-user mode:

You are trying to work with a company file that is located on another computer, and this copy of QuickBooks cannot reach the server on that computer. (H202).

Open in new window

  1. I can ping between all of the workstations and the QB server by DNS name.
  2. I have been able to cause 100% packet loss by setting the packet size to anything over 23,672 bytes.
  3. Does the 23,672 byte limit make any sense regarding the H202 error and/or does it imply any kind of network problem?

The standard payload of IP in an Ethernet frame is 1500 bytes. Any ping over 1500 bytes will fragment and cause more than 1 Ethernet frame to be created. At that point, your mileage may vary. Pinging with such large pings isn't really a good test since your TCP/IP stack is making 1500 byte packets anyway. Of course, these rule don't apply in storage networks that use jumbo frames.
