Make two A host RRs with the same name and two different IP addresses.

Forgive me for being kind of new at this.. RRs? The
request came from someone using a couple ports on one
machine and another port on another machine...

There are two services running on two machines. First
service is running on Server1:7001 and the second on
Server2:7002
We would like to access these two services with one single
DNS name...

It is easy enough to make two RRs pointing to two different IP addresses DNS
will use round robin to hand them out but but you may get inconsistant
behavior. Do you access these services in a web browser by typeing
http://machine.domain.com:7001 and http://machine.domain.com:7002 ?
As I said, it is easy enough to make these records just open the domain.com
Forward lookup zone and create two host of the same name and give them the
IP addresses of the two machines.

I tried to create the RRs, but because they were both the
same IP address it would not let me. Is there any way to
specify port number?
Im trying to create two records for:
10.1.182.113:7003
10.1.182.113:7020
same IP address it would not let me. Is there any way to
specify port number?

You cannot have to records with the same IP address in DNS, same name you
can, but not IP address.
I was afraid of this, you cannot specify a port in DNS, the port used is up
to the application you are using, in this case browsers use port 80 unless
you add the port after the domain name.
What are you trying to accomplish, exactly?
There may be another way, but this really needs to be posted in the IIS
group.

Here is the email I got from the user..
In such case can u give a DNS name for 10.1.182.113 and
10.1.182.171

This you can do:
site1 A 10.1.182.113
site1 A 10.1.182.171
DNS will use Round Robin to give these out.

Would I need to change the name of the machines as well?
If I try wont it say that the machine name is already on
the network?

Are you trying to connect to web servers on these two machines?
Or connect to the machine by a different name.

Heres his answer...
Actually I have installed applications on these two
machines (WebLogic Application server). I will be using
these two with one DNS name.

That's not a problem, in the forward lookup zone for the domain you want,
but let's say it is example.com, create two "A" hosts you can name it
weblogic, if you want, then give them the IP for each machine. Then you can
access them by weblogic.example.com. The problem I see with this is DNS will
use Round Robin to give the IP out, it will aternate first one then the
other, so you don't really know which record you are going to get. Since the
two boxes answer on different ports it will be inconsistent behavior, with
connecting.
What would make more sense if they were both on the same port then you could
make two records like weblogic1 with one IP and weblogic2 with the other IP.
If the applications were listening on port 80 you would not need to enter a
port because browsers default to port 80.
you would just use weblogic1.example.com and weblogic2.example.com.
