After apply RU1 for Exchange 2007 SP3 we cannot create a Receive Connector

When we try to create a new receive connector in Exchange 2007, we received the error:

New-ReceiveConnector : Active Directory operation failed on testgdc1.company.com. This error is not retriab

le. Additional information: The parameter is incorrect.

+ new-ReceiveConnector <<<< -Name 'TEST' -Usage 'Custom' -Bindings '10.1.2.30' -RemoteIpRanges '192.168.0.2' -Server 'TESTHCEX1'

The accepted solution is
From Exchange 2007 SP3 source and with Schema admin permissions

C:\Source\Ex2007-SP3>setup /ps
Welcome to Microsoft Exchange Server 2007 Unattended Setup
