Error: "The specified user couldn't be found" when joining computer to AD domain

Reid Montague

Hi everyone, I encountered an Active Directory issue at work and would like to seek advice from the experts here.

When trying to add a new computer to our Active Directory domain, the system reported the error: "The specified user couldn't be found." I would like to ask: Is this error directly related to the number of AD users exceeding 1000? What specific mechanism or restriction causes this?

Is this the error log you encountered? I'm facing the same issue. Please help resolve it.

Based on the error you're encountering, it's highly likely that the number of objects in your Active Directory has exceeded the default LDAP query size limit.

To resolve this, you will need to modify the MaxPageSize parameter in your domain controller's LDAP policy. This adjustment will increase the maximum number of objects returned in a single query.

You can follow the detailed steps provided in this technical guide:
