Lync and IIS ARR (Application Routing Request)

Hi all,

Glad to see many has found my blog and that is why it’s nice to share things πŸ™‚

Yesterday I installed an reverse proxy with IIS AAR 3.0 on Windows Server 2012 R2.
Word of advice on this is that dont do it!

I couldn’t get it to work. Instead when I installed AAR 2.5 + the hotfix everything worked like a charm.

The setup is identical with 2.5 and 3.0, don’t worry. The biggest deal is publishing externally. Based on the mobile logs I found that reverse proxy wont pass all information on webtickets to the mobile client and that is why they wont sign-in.

So download IIS AAR 2.5:

Hotfix for IIS7:
And for IIS 8:

I wont be making instructions how to configure it, because the are so many out there.

Easy one:
