Tech Short: How To Change The MTU – Server 2016

 

Troubleshooting an application issues which could possibly be network related.  I found myself needing to make some adjustment to the maximum transmission unit (MTU) setting of my server.  As such what better time to post a quick technical short on how to go about doing this.

 

How To Change The MTU – Windows Server 2016

Requirements:

  • Logon and Administrator permission on Server
  • Network Connectivity
  • Time to reboot

 

Procedure:

From the desktop of your Windows Server 2016 server open an Administrative command prompt by Right-Clicking on the start button and select  – Command Prompt (Admin).

Once in the command prompt you we be using netsh to determine the IDX of the installed interface devices. this is performed by using the following command:  netsh interface ipv4 show interfaces

Take note of the IDX interface that you would like to change the MTU on as this is what we need to specify when changing the MTU settings.

Using netsh again you issue the following command: netsh interface ipv4 set subinterface “number-goes-here” mtu=1400 store=persistent

Please note that the subinerface will be the IDX number from the first netsh command and that the MTU setting is a value less than the original 1500.

Now you can reboot to have the changes take effect.  I have also noticed the disabling the interface and  re-enabling also works.

 

 

How to demote a Windows Server 2012 Domain Controller

In this short write up I will go over steps to demote a Server 2012 domain controller.

If you have worked in Active Directory and Windows Domain Administration over the years you may recall that in previous version of Windows Server that you would use the command line tool of ‘DCPROMO’ to promote or demote a server. Since Server 2012, the use of DCPROMO has been deprecated. In fact, if you attempt to use it you will be inform of this via the Active Directory Domain Service Installed.

In Server 2012 and later versions the use of Server Manager or PowerShell is required to promote / demote a server to/from a Domain Controller (DC). Below I provide steps on how to demote a server with some illustration along the way. Also, here is a quick YouTube video on the process: https://youtu.be/sBK2_APaDdg

Log into the domain controller you intend on demoting and Launch the Server Manager, select the Manage drop down menu, select Remove roles and features.

On the server selection page, select the desired server from the pool.

On the Remove Roles and Features Wizard, un-tick the Active Directory Domain Services box

The Remove Roles and Features dialog box will open. Click Remove features

On the Remove Roles and Features Wizard dialog box Validation Results box will appear. The domain controller must be demoted before continuing. Click on Demote this domain controller.

On the Active Directory Domain Services Configuration Wizard enter the required credentials to demote this server, click Next.

You will have several removal options. From the forced remove of failed domain member, to removing of the last domain in your forest. Make the selections which is appropriate for your remove task and click Next

Finally you will arrive on the New Administrator Password, enter and confirm the new local administrator account password, click Next.

On the Review Options verify the information is correct and click Demote.

After the server has restarted it will no longer be a domain controller

And that is it.
