MS15-034 and MS15-033 April Critical Patches

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.

BR,

Irwin

Hi,

MS15-033 is for Office/SharePoint only https://technet.microsoft.com/en-us/library/security/ms15-033.aspx (may require restart)

MS14-034 is for http.sys (IIS etc) https://technet.microsoft.com/en-us/library/security/ms15-034 (does require restart)

For questions relating to specific product updates, it's best to ask in the relevant product forum (e.g. Lync or Exchange)

Hi, Don. Good Day! Should this patches be really installed immediately? Or this could wait for a couple of months? Thank you. BR, Irwin
