With November 2015 public CAs do not issue new certificates that uses internal names or reserved IP addresses in
subjectAltName or in
commonName. Furthermore such certificates will be revoked on October 1st, 2016.
Internal names are hostnames that do not end with an Top Level Domain ending (.com, .de, …). For example: .local, .internal. Also NetBIOS names without any domain extension are affected.
Reserved IP addresses are defined by Internet Assigned Numbers Authority (IANA). You can look reservations for IPv4 here (RFC 1918 range) and IPv6 here (RFC 4193 range).
If you are using an internal CA you are not affected. For more information about this change of public CAs click here. For more information about VMware products click here.
Here is a short list of possible issues that can result in a black screen when trying to access your VMware Horizon View desktop.

Information about View Linked Clone Desktops are stored in 3 locations: LDAP DB, View Composer DB, vCenter DB. In the past (versions 3.x, 4.x) it happens more often to get orphaned desktops or VMs that shows errors or state “missing”. In more current versions of VMware View at one hand this happens not that often any more and on the other hand it is often self repaired after trying to delete these faulty VMs a second time in GUI. But it is still possible to get an VM that shows errors and you are not able to delete this VMs in the GUI.
I will show how to delete such VMs without deleting the object in every of the 3 locations manually.

I had a strange behavior in a vSphere Cluster with View Linked-Clones. The problem was that it was not possible to vMotion a Linked-Clone VM to an other host. The error was like:
Cannot open the disk '/vmfs/volumes/11111111-22222222-3333-444444444444/VDI-1/-VDI-1-000001.vmdk' or one of the snapshot disks it depends on.
I could not find any problems by checking snapshot chains. So I investigated Replica-VMs. vCenter allowed tasks like Power On and Editing which is normally not allowed for Replica-VMs. This state of related Replica-VMs seems to prevent vMotion tasks. I took the following steps to solve the problem.

Here are some very useful links and commands to implement and troubleshoot Microsoft KMS (Office and Windows).
Steps to install KMS for Windows (Link: here):
- Install KMS Server, install the KMS Key:
slmgr.vbs /ipk kms-key
You should get an success-message after a few seconds. If not, maybe the key is not an KMS Key or the wrong key.
- Activate the KMS Server online:
- Check Information about the service
slmgr.vbs /dlv (less information)
slmgr.vbs /dli (more information)
Steps to install KMS for Office 2010 (Link in german: here):
- Download Office 2010 KMS Host License Pack here and install it on KMS Server. During the installation you fill in you KMS Key for your Office 2010 license.
- Check Information about the service
slmgr.vbs /dlv all (for Windows and Office)
slmgr.vbs /dlv bfe7a195-4f8f-4f0b-a622-cf13c7d16864 (just for Office)
Stuff for troubleshooting:
When you upgrade Horizon View, you have to upgrade all Connection Servers within the environment. When you just have one, it is clear you will have a downtime. But even when you have n Connection Servers, you have to stop the View Connection Server services of ALL servers at once! This WAS right, but now you can upgrade one Connection Server after the other, without stopping all services of all servers at once. This new procedure you can find in the current upgrade guide here. Take care you download the latest version of the document (ID EN-001476-01) because previous versions – including EN-001476-00 – still want you to shutdown all services.
