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.
15.0.4433.1506
0x80004005

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

Microsoft reports several TechNet article:
http://support.microsoft.com/kb/240797/en-us
http://support.microsoft.com/kb/909738/en-us

So you need to change the ActiveX Control Settings for Lync 2013 Client:

SOLUTION:

Go and delete both registry keys. A reboot is not necessary and it will work.

In Windows 7, Windows 8 and Windows 8.1 they are hidden here:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}

    Hi All,

    If deleting the registry key don’t fix the issue please try this:

    Run PowerShell
    Copy and paste these lines:

    Set-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}” -Name “Compatibility Flags” -Value 8388608
    Set-ItemProperty -Path “HKLM:\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}” -Name “Compatibility Flags” -Value 8388608

    Please tell me if it works.

      It worked for awhile, then the Value 800000x changes to 800400x after Windows 10 updates. If I delete the key altogether, it reappears after some time. I never know if Skype for Business will work or not, it's unreliable :(

      Hi Bijo,
      could you send a contact request via the form on my blog please. I will have to exchange in your case some data, because this keys must be present. You als can try setting those keys manually for an initial test.

    Both fixes work for a while but after a Windows update, the entry comes back if it was deleted or the value changes back to 00000400 and the issue comes back. So i just apply the fix again. Any ideas?

How to hide users from GAL if they are AD Connect synchronized

How to hide and un-hide users from Global Address List (GAL) in Exchange Online if they are AD Connect synchronized Hiding User from GAL isn't possible if those are synchronized form On-Premises Active Directory. The local AD is the leading system for all important attributes, like SMTP, UPN and hiding from GAL. Especially during a cross-tenant migration, you do not want to see not migrated user in the GAL. Those User aren't actively working until their cut-over day. Since the Exchange Online attribute  msExchHideFromAddressList s is an AD on-premises parameter, we have two possible ways hiding user in BME from GAL.   Modify the AD Connect for your teant with a custom rule, by using a extensionAttribute to set the HidefromGAL. In this rule, for users which have an entry in the extensionAttribute, hiding / un-hiding will be controlled by AD Connect This is the best option for Cross-Tenant Migration, if you run 2 or more AD Connect system We direct modify the AD hide at

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 fo
