Lync 2013 Client, Desktop Sharing shows blank screen (Windows 7, Windows 8, Windows 8.1)

I came across this problem, where a customer reported:
A user could not participate on desktop sharing session, neither in conference nor in a p2p session. Other video related submission were working, like video or white board.
First I was guessing it could have been the video driver, but if video in Lync was working it didn't sound quite logic.

After investigating this problem, I saw a ActiveX blocking Error Message in the Eventviewer:

Microsoft Lync
CLSID: {00000000-0000-0000-0000-000000000000}
CATID: {9B179D6E-9BDB-454b-BE3D-89F9A792BD39}
The ActiveX Compatibility setting disabled loading this object to help protect your security.

This let me investigate more closer into Internet Explore. Well even there is couldn't see anything directly:

Microsoft reports several TechNet article:

Cannot join external Lync Meeting: Lync Edge Server Single IP Address (Lync Edge Server Single IP Web Conferenceing Problem)

Lync Edge Server FQDN and IP PORTS(Version 1.2, Update 26.11.2014)

As we all know, we can configure Lync Edge Server in several way.

1) Single Edge Server with a SINGLE IP ADDRESS
2) Single Edge Server with MULTIPLE IP ADDRESSES (3x IPs)
3) Multiple Edge Server in a Pool, with MULTIPLE IP ADDRESSES (Zx 3 IPs)

Regardless what we are going to configure, there are common / well-known TCP Port necessary making Lync work, which are:

Access:
Port: 443 and 5061

Conferencing:
Port: 443 and (444)

AV:
Port: 443

(I have not listed other ports, e.g. STUN or the dynamic port range. This is not required for the topic discussed here)
External FQDN with single IP address:What can we see here? If we are going to choose a single IP address, we would have TCP Port overlapping. Therefore the only way avoiding this is assigning other ports.
Additionally we will also see and are reminded that Lync highly depends on DNS. If we have single IP, we must have use single, unique FQDN for all services.

E.g.:
ACCESS:
