We're getting ready to install several SAP applications (ERP, Portal, SolMan, etc.) on Windows 2012 R2/SQL Server 2012 SP1/VMWare environment. We are going through the prequisite checks. We would like to install the systems on virtual hosts as mentioned in SAP Notes 962955, 1282975, and 1564275. We are using DNS for hostname resolution for all of our systems.
We have followed the steps in the notes including creating the DNS A-record and the PTR record pointing to the reverse lookup zone file for the virtual hostname mentioned in SAP Note 129997. However, it seems after a short period of time that the virtual hostname in PTR record is overwritten with the physical hostname. Thus, the nslookup and niping tests are failing as they are bringing back the physical hostnames. For example see the screenshot below.
Has anyone ran into this issue? Please advise if we are doing something incorrectly.
Thank you!
