Changing the Client Push Install Account using Powershell

[NullSID]

So, I have to change the account currently being used in SCCM for client installation.

I have created the new account.

I can add the account using the gui under Administration > Sites > Right click Sites > Choose Client Push Install Settings > Accounts. But I cannot do it through Powershell. If I run the following command:

Set-CMClientPushInstallation -SiteCode 000 -ChosenAccount "domain\account" I get the error "The networkaccessaccount: domain\account does not exist. input an existing one.

Any suggestions? The account I'm using has full access to ad.

 

Thanks everyone!

So I got the account added. You run the powershell command on the secondary site. it just needs to be added in accounts first.

So the next question is, how do I remove the old account?
