DNS / Nameserver Settings

TDP 5.3 Win10

A recent security update is causing a name resolution error for Teradata alias'. Our server alias isn't being resolved. The fix is to use an FQDN instead of the alias. In Teradata SQL Assistant, if we set the Data Source DNS Entries value to a single digit integer, there are no connection issues. I'd like to find something similar to workaround for TDP.

Of course it works for basic reporting to update the connection properties to the FQDN but the txp/tim TRL references are still to the alias which of course breaks the report process.

We're still looking for a fix but any suggestions here would be greatly appreciated.

Error is:

This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server
