In earlier versions of Exchange you can use the Autodiscoverredirect option to retrieve autodiscover information if your primary SMTP domain in your email address does not match the domain name of the autodiscover DNS record in your Exchange deployment. You’ll face this issue when your Client Access server is using webmail.contoso.com and autodiscover.contoso.com but your email address is firstname.lastname@example.org. In this case your Outlook client will automatically start looking for a DNS record called autodiscover.fabrikam.com which points to the autodiscover.contoso.com. As a result a certificate warning is presented since the name of the request does not match the name on the certificate.
During a migration project I ran into a nasty issue where I was not able to perform any outbound calls via the mediation server and the SIP trunk. As soon as I entered a phone number in my Lync 2013 client and hit the ‘dial’ button the call failed, immediately.
Ok, I couldn’t resist it… In my previous blog I wrote about publishing Lync services using a Kemp Load Master. Since I’m not married to Kemp (although you might think differently, and so does Marco 😉 I also have an F5 LTM up-and-running in my lab. Time to have a closer look at the F5 when it comes to reverse proxy with Lync 2013.
Again, in my lab I have a Lync 2013 Enterprise Edition, in the perimeter network I have a Lync 2013 Edge Server, but I will use an F5 LTM load balancer.
In my previous blog I wrote about publishing Lync services using IIS/ARR as a replacement for TMG 2010. It is also possible to use a hardware load balancer to publish these Lync web services to the internet. In this blog I’ll talk about using a Kemp LoadMaster LM2600 for publishing Lync web services.
In my lab I have a Lync 2013 Enterprise Edition, in the perimeter network I have a Lync 2013 Edge Server, but instead of IIS/ARR I now have a hardware load balancer.
In an earlier blog post I wrote about publishing Lync services using TMG 2010. One of the Microsoft alternatives for reverse proxy is the Application Request Routing module or ARR, a module that’s running on top of Internet Information Server (IIS).
