SYMPTOMS

Consider the following scenario:
  • You deploy a read/write domain controller in a central office. And you deploy a read-only domain controller (RODC) in a branch office that is located at a different location from the central office. Both domain controllers are running Windows Server 2008 Service Pack 2 (SP2) or Windows Server 2008 R2 Service Pack 1 (SP1).
  • You cache only the passwords of the user accounts that are for the branch office on the RODC. The related passwords of the computer accounts are not cached on the RODC.
  • In the branch office, you log on to the domain by using a smart card.
In this scenario, all NTLM authentication requests from user accounts fail. Additionally, you are prompted to input your user name and password when you try to access a resource in the domain. For example, you are prompted for credentials when you try to access a shared file or a web server by using the IP address of the computer that hosts the shared file or the web server.

Note Kerberos authentication requests from user accounts in the branch office succeed. Therefore, you are not prompted when you try to access the shared file or the web server by using the computer name that hosts the shared file.

CAUSE

This issue occurs because read/write domain controller does not return the NTLM user passwords for user accounts to the RODC. Therefore, all NTLM authentication requests fail.

RESOLUTION

To resolve this issue, install this hotfix on the read/write domain controller that is running Windows Server 2008 Service Pack 2 (SP2) or Windows Server 2008 R2 Service Pack 1 (SP1).
