One of my windows admins claimed: "Windows 2008 DNS server can't assign 2 names to one IP address". Besides the fact that you could use a CNAME to accomplish that, I'm sure (having worked with all sorts of other DNS servers) that it should be possible to add multiple A (or AAAA) pointing the the same IP address.
Can someone confirm/clarify that for me?
Thx

Here is a partly-redacted screen capture of two A records on one of our Windows Server 2008 DNS servers:
As you can see, there are two different names in two different A records with the same IP address in both records. I just created this image in the last ten minutes. There are several other examples all over our Windows DNS servers of this.
The admin who claimed otherwise was either completely wrong or spoke in a confusing way that made it seem like they said something completely wrong.
Note that the converse is also possible. It is possible to have two or more A records with the same name but different IP addresses. Not only is this possible, it's essential for proper functioning of a Windows 2000 or later domain.
