PowerShell is required to create a service account. Once created it can be managed in the GUI.
#Create the MSA
New-ADServiceAccount -Name MyAppSrv -RestrictToSingleComputer
#Add the Machine to be used with the account
Add-ADComputerServiceAccount -Identity SRV-01 -ServiceAccount MyAppSrv
#You can test to see if it is working (it won't... yet)
Test-ADServiceAccount -Identity MyAppSrv
#Finally, install the account and test again
Install-ADServiceAccount MyAppSrv
Test-ADServiceAccount -Identity MyAppSrv
#Next, Configure the service to use the account.
Go to your service you wish to run on a service account, on the logon tab, set the credentials for the service as a network account. Use the browse button to find your MSA. Remove the pre-populated password from the fields and save.

Problem
A Windows server hangs, reboots, becomes unresponsive or network clients disconnect due to Dns.exe consuming a large amount of nonpaged pool memory and file handles.
Solution:
Log on to the server using the local or domain Administrator account, open an elevated command prompt and perform the following steps.
1. Press the Windows Logo+R, type runas /user:[email protected] cmd where domain.local is replaced by the name of the Active Directory domain or local server name and press Enter. The same task can be accomplished using the Command Prompt and Run as Administrator.
2. Type the Administrator account password when prompted and press Enter.
3. Type dnscmd.exe /config /socketpoolsize 1000 and press Enter.
4. Type net stop dns && net start dns and press Enter.
