Hi,

We would like to leverage on NLB and preconfigure the CAS for DR purpose at DR site

Once setup the Windows NLB, will use
get-outlookanywhere -server $server |select internalhostname (set internal hostname to tcluster’s FQDN)

After that, we will shutdown the the Exchange server @ DR site.

Using this DR method, do we require additional exchange license.

No one on this site can give you an answer on licencing questions - only Microsoft can.
Therefore you need to call Microsoft, ask them and get the answer in writing.

However, the Exchange product team does not recommend WNLB for use with Exchange, mainly because it sucks quite badly.

Furthermore, Exchange expects all servers to be active, and if you shutdown the remote server then it will complain. I presume that you have the mailbox role already in your DR site? If so, just add the CAS role to that server. In the event of a site failure, change the DNS records.
If you have a short TTL time on the DNS records then the change will be effective very quickly.

Thank. Yes - we have all in-one installation @ DR site. If we use DNS, understood that the Exchange management console can not run.

Not in my experience.
The console will connect to the local machine.

Which version of Exchange are you talking about? If Exchange 2013, then https://localhost/ecp should work.

However in the designs that I do, I always have site specific URLs, as well as the generic URL. Then the problem doesn't occur anyway.

Don't lose your head updating email signatures!

Do your end users still have the wrong email signature? Do email signature updates bore you or fill you with a sense of dread? You can make this a whole lot easier on yourself by trusting an Exclaimer email signature management solution. Over 50 million users do...so should you!

Yes. It is Exchange 2013. Understood that DNS method for DR purpose only have issue with Exchange 2013 and not prior version.

Our understanding was that using DNS method - the management console and Mobile device will have problem (we dont have mobile in our case).

Will check out.

I have never seen a problem with management console connection using the DNS methods. You can eliminate any chance of a problem by having a unique site URL for each server then having a general URL.
WNLB isn't really going to help anyway, as it doesn't work well over cross site.
