I have opened the new question as Jeff asked me to ...

I indeed would love to download the EBF ... but since the absorption into SAP, which we were not told about (go figure why?), we can no longer download those EBFs ...

Ironically, no one can even tell us how to PAY for a support contract.

Here's the link back to the original question:

FYI, this issue is exactly the same for both SQL Anywhere 12 and 16 from the 'bad' machine. Finally, I did try with the ip address, without host name - same exact result.
