Disabling IPv6 And Exchange – Going All The Way

Posted on 29th October 2014 by Rhoderick Milne [MSFT]

When we are performing the Exchange Risk Assessment, one of things PFE love to check is how servers have been configured for IPv6. There have been numerous occasions where we have found servers whose admin has said that they have disabled IPv6, but when you look at the server it is not really disabled.

When we take a look at the Exchange server, the initial clue is that the network card’s TCP/IPv6 … Read the rest “Disabling IPv6 And Exchange – Going All The Way”

Using ADPropertiesOnly With Exchange Virtual Directory Cmdlet Shows False Positives

Posted on 12th September 2014 by Rhoderick Milne [MSFT]

Previously we discussed an interesting feature of the Exchange virtual directory cmdlets where they check data stored in AD, rather than making a trip to the server and querying its IIS metabase. For the details on this, please read the original post here: Slow Response To Exchange Virtual Directory Cmdlets.

In that article we were using the ADPropertiesOnly switch so that it was very quick to… Read the rest “Using ADPropertiesOnly With Exchange Virtual Directory Cmdlet Shows False Positives”

Set AdminSessionADSettings ViewEntireForest To True By Default

Posted on 8th September 2014 by Rhoderick Milne [MSFT]

In Exchange 2010 the Set-AdServerSettings cmdlet is used to manage the AD environment in the current Exchange Management Shell (EMS) session. In Exchange 2007 there was a variable called AdminSessionADSettings for the same purpose. Exchange admins normally use the Set-AdServerSettings cmdlet to change a session’s view scope, so that they can see objects in multip… Read the rest “Set AdminSessionADSettings ViewEntireForest To True By Default”

Retrieving Packets Received Discarded Perfmon Counter From Multiple Servers

Posted on 18th July 2014 by Rhoderick Milne [MSFT]

Whilst working on a customer’s Exchange 2010 DAG issue, I wrote a quick script to quickly grab some performance monitor counters from all of their Exchange servers. The issue that we were investigating was related to discarded packets when the VM was running on a certain hypervisor host. The customer had moved their Exchange VMs to a new host and after doing so they were experiencing cluster iss… Read the rest “Retrieving Packets Received Discarded Perfmon Counter From Multiple Servers”

Exchange and AntiVirus Exclusions – Still A Critical Conversation

Posted on 30th June 2014 by Rhoderick Milne [MSFT]

In a previous post we saw the Microsoft requirements for the exclusions that must be added to file system AV on Exchange servers.

In the aforementioned post the majority of the… Read the rest “Exchange and AntiVirus Exclusions – Still A Critical Conversation”

Exchange Scripting Agent – The Power Of Script

Posted on 24th June 2014 by Rhoderick Milne [MSFT]

Exchange 2010 introduced a very interesting feature – the Scripting Agent. The intent for this component is to provide extensibility to the base management tools and ensure consistency for the execution of cmdlets in the environment. The feature is not enabled by default and you must manually enable it if you want to leverage the Scripting Agent.

If you are looking for a way to set default optio… Read the rest “Exchange Scripting Agent – The Power Of Script”
