  1. Open Command Prompt on a domain controller (You must use admin credentials)
  2. Type NTDSUTIL and press ENTER.
  3. In the ntdsutil: prompt, type ldap policies
  4. In the ldap policy: prompt, type connections
  5. In the server connections: prompt, type connect to server <FQDN of domain controller> (example: connect to server domain1.com)
  6. Once you are connected, type q to come back to the ldap policy: prompt.
  7. To change the value to allow up to 5,000 objects to be returned in a single LDAP query, type set MaxPageSize to 5000
