I recently wrote a couple of Knowledge Base articles that are intended to explain why an HIS Server logs one of the following event messages:

- Event ID: 23

- Event ID: 230

These are very common errors that occur when using HIS Server especially if you still use the 802.2 DLC link service to connect to IBM host systems via the DLC protocol.

The articles also contain troubleshooting steps that can help you capture diagnostics information that the HIS Support Team requires when working on these types of problems. You may also be able to use the diagnostics to determine the root cause of the problem to resolve it without needing to call support.

I hope the information in these articles is helpful.

Thanks…
