Hi, Gayam,

For changing service account for Search Administration Web Service for Search Service Application, you can go CA> Application management>manage service applications, choose your search service application and click on properties on Ribbon.  Find the application pool the search admin web service locate.

Go security>configure managed accounts. Register the new account as managed account if you do not find you account here.

Then go Security>configure service accounts. Choose the search service and the application pool holding search admin web service. Change the account to the one you want.

Hi, Gayam,

Try to use this script, make sure the account you use is registered as a managed account:

$MgtAccount = Get-SpManagedAccount -Identity "Domain\ManagedAccountusername"

$procId = (Get-SPEnterpriseSearchService).get_ProcessIdentity()

$procId.CurrentIdentityType = "SpecificUser"

$procId.ManagedAccount = $MgtAccount

$procId.Update()

I have tested it in my environment and it works good.

Best Regards

Hi, Gayam,

You do not need to change the script except the user account. “$procId = Get-SPEnterpriseSearchServiceApplication -Identity "Search Service Application"   #” is not needed and not included in the script I provide.

Also do not forget to change the domain to your domain name.

$MgtAccount = Get-SpManagedAccount -Identity "Your domain name\ managed account name"

$procId = (Get-SPEnterpriseSearchService).get_ProcessIdentity()

$procId.CurrentIdentityType = "SpecificUser"

$procId.ManagedAccount = $MgtAccount

$procId.Update()
