Error after installing search service application

Question

I got this this error after setting up Search Service Application with Powershell.

The search service is not able to connect to the machine that hosts the
administration component. Verify that the administration component
'a23fd668-f823- 4ab2-b0fc-b0baebfd4af2' in search application
'SharePoint_Search_Service' is in a good state and try again.

The Sharepoint Search Service was showing error when I visited

Central Administration->Application Management->Service Applications-> Manage Service Applications

Here is the powershell script used

$App1 = "APP-Server-01"
$APP2 = "APP-Server-02"
$SearchAppPoolName = "SharePoint_SearchApp"
$SearchAppPoolAccountName = "EXSERV\Administrator"
$SearchServiceName = "SharePoint_Search_Service"
$SearchServiceProxyName = "SharePoint_Search_Proxy"
$DatabaseName = "SharePoint_Search_AdminDB"

Create a Search Service Application Pool

$spAppPool = New-SPServiceApplicationPool -Name $SearchAppPoolName -Account    
$SearchAppPoolAccountName -Verbose

Start Search Service Instance on all Application Servers

Start-SPEnterpriseSearchServiceInstance $App1 -ErrorAction SilentlyContinue
Start-SPEnterpriseSearchServiceInstance $App2 -ErrorAction SilentlyContinue
Start-SPEnterpriseSearchQueryAndSiteSettingsServiceInstance $App1 -ErrorAction  
      SilentlyContinue
Start-SPEnterpriseSearchQueryAndSiteSettingsServiceInstance $App2 -ErrorAction 
      SilentlyContinue

Create Search Service Application

$ServiceApplication = New-SPEnterpriseSearchServiceApplication -Partitioned -Name   
    $SearchServiceName -ApplicationPool $spAppPool.Name -DatabaseName $DatabaseName

Create Search Service Proxy

New-SPEnterpriseSearchServiceApplicationProxy -Partitioned -Name  
    $SearchServiceProxyName -SearchApplication $ServiceApplication

Search Service Application error

Answer 2

I actually discovered the reason for the errors, you need a domain account not a local account to create a search service application. Use an active directory created domain account to create the service appplication.
