SAS TDT Connection Failure: "name not in HOSTS file"

Dear Teradata Community,

I got a failure message - "name  in HOSTS file" - when trying to connect from SAS to Teradata Platform.

The current architecture is using a DNS server performing translation between IP adress of the different nodes and an "alias name - AN -" issued in the logon string connection.

(1) Connection from SAS Server to Teradata Platform is operational using BTEQ

(2) Issuing a "ping AN" command from the SAS Server returns a "Teradata node adress"

(3) Substitution of the AN by that "Teradata Node adress" in the "SAS connection order" is operational too !

Does that mean that SAS application still use the HOSTS file to connect ? Do I have to fill that file with the different cop"i" adress ?

Thanks a lot for any kind of help you can give me,

Didier.
