Hi, Guys.

Good Day!

We would like to ask for your assistance on this.

Are the MS15-034 and MS15-033 Critical Security Patches that were released last April so critical that needs to be installed in your servers? If so, on which servers are they applicable? Servers that have IIS? Or do you need to patch them to all your servers?

How do you patch them on both Lync Edge and Frontend servers? Do you need to failover something before you patch these servers? Kindly let me know the process/procedures in doing this.

Further, how do you patch also the Exchange Edge servers for this instance? I see that our Exchange Edge servers have IIS installed on them. Again, any failover requirements before you patch these servers? Please advise.

Your help is much appreciated.

Thank you.

Hi,

I will always patch all server with security patches.

Depend on your enviroment you should patch server by server.

In a Lync enviroment, if you have a Enterprise pool installed (at least 3 server) and an Edge pool (at least 2 server)

You can shutdown the Lync serverices gracefull on the first server update the server, start the services and take the next server. This is the same on the Edge server.

As long as you patch one server the services will not be available for this s

Hi, Guys.

Good Day!

How do you reboot the Lync 2010 Edge server prior to MS15-034 patching? Please advise.

Could you someone help me on how to do this?

Thank you.
