Geekin' Things

by Brannon Breau

Have to start somewhere.

I have decided to document my journey into making a test environment for my own learning needs and wonders.

I am not a professional writer, I work as a ServiceNow System Admin at the time of this post. I have a background and college education in Network administration and I’m learning development of ServiceNow.

Why am I creating this test environment?

1. To continue learning about servers, Active Directory, computer management.

2. To learn how to develop in Servicenow and to integrate into a real world IT environment.

3. Because I have the servers sitting around and this seems like a good reason to use one.

Hardware Setup

I will be using a Dell PowerEdge R710 for this project.

– Duel Intel x5670 Zeon processors 2.93 GHz
– 48GB Ram
– 3 1TB 5400RPB WD Blue HDD 2.5″

Software Setup

I will be running Windows Server 2012r2 Datacenter edition. Hyper-V will be used to setup the virtual servers and desktops. I will setup 4 servers and 4 desktops. You might be asking “why DataCenter edition”? that is because of 2 reasons. 1. I got a copy of it from when I was a student in college. 2. A feature of the Datacenter version of 2012r2 is that you have unlimited Hyper-V instances of Window Servers (limited to only what the hardware can handle)


– Windows Server 2019 Standard. Setup as the Domain Controller.
– Windows Server 2019 Standard. Setup as the ServiceNow MID Server.
– Windows Server 2019 Standard. Setup as a file server.
– Ubuntu Server 18.04.3 LTS. Not sure what I will set this one up as

I have added a Linux server to the mix to have the environment more realistic as my current company has both windows and Linux servers.


– Windows 10 Pro
– Ubuntu Desktop 18.04.3 LTS

I included a Linux desktop to see how it reacts with the windows environment and it’s the closet thing to a Mac that we can have in testing.

As you see there is a lot of setup to be done. Setup the main host Dell, each one of virtual machines, setting up Active Directory and populating that with users & groups. Also have the setup of the ServiceNow developer instance, setting up the MID server and connecting the two. Then setting up the LDAP connection between ServiceNow and Active Directory.

Please leave comments of what you think.
