Hyper-V Server Change Account Lockout Policy Settings With Powershell or Command Line

How to Change Password Policies In Hyper-V where gpedit.msc does not work? 

There is easy way of doing this. Just check tutorial below..

 The discovery of this info, from 'net accounts,' ultimately worked for me, and I was able to write a script that quickly displayed the Lockout policy info. Here is the output from 'net accounts':..

PS C:\Users\Freemium> net accounts

Force user logoff how long after time expires?:       0

Minimum password age (days):                          1

Maximum password age (days):                          60

Minimum password length:                              14

Length of password history maintained:                24

Lockout threshold:                                    3

Lockout duration (minutes):                           15

Lockout observation window (minutes):                 15

Computer role:                                        WORKSTATION

The command completed successfully.

This code snippet was created to get the info into a variable:

$lockoutObj = net accounts | Select-string threshold

$lockoutStr = $lockoutObj.ToString()

$lockoutStr -match '\d{1,3}' | out-null

$LO_threshold = $matches[0]

PS C:\Users\Freemium> echo $LO_threshold

3

If you need to set the lockout threshold use this command (elevated priv. needed):

PS C:\Users\Freemium> net accounts /lockoutthreshold:10

The command completed successfully

PS C:\Users\Freemium> net accounts

Force user logoff how long after time expires?:       0

Minimum password age (days):                          1

Maximum password age (days):                          60

Minimum password length:                              14

Length of password history maintained:                24

Lockout threshold:                                    10

Lockout duration (minutes):                           15

Lockout observation window (minutes):                 15

Computer role:                                        WORKSTATION

The command completed successfully.

There are the options: 

NET ACCOUNTS

[/FORCELOGOFF:{minutes | NO}] [/MINPWLEN:length]

              [/MAXPWAGE:{days | UNLIMITED}] [/MINPWAGE:days]

              [/UNIQUEPW:number] [/DOMAIN]

You just change lockouttreshold to /maxpwage:20 and thats it.
