Skype for Business mobility and hair-pinning requirements

Mobility Service URL Requirement

In a default configuration, a user who is connected to the internal network via Wi-Fi will always be returned the external Mobility Service URL for his/her home pool. The user’s device must be able to query the internal DNS zone and resolve the external Lync Web Services FQDN to the IP address of the external interface of the reverse proxy. The user will then make an outbound, hair-pinned connection to the Mobility Service through the reverse proxy.

When you add or remove a server to the pool in your topology and then publish the updated topology, it will cause all of the servers in the pool to restart at the same time. While the servers are restarting the pool is offline, which will interrupt service for your users connected to that pool. To prevent any interruption of service to users, plan to publish the topology with the new server in the pool during non-business hours.

Windows 2019 server activation error

With a correct key, we can not activate Windows 2019 server:

The workaround is to do with command line - run as administrator:

slmgr.vbs /ipk   key-key-..
