Installing Sophos Anti-Virus fails on a Windows Server 2008 read-only domain controller (RODC) and you see error 3051 in the Sophos log.

First seen in
Sophos Anti-Virus for Windows 2000+

Operating system
Windows Server 2008 (32-bit) Standard RODC

What To Do

Installation fails on a read-only domain controller because the installation program cannot create an auto-update account.

You must create the AutoUpdate account manually so that Sophos Anti-Virus can automatically download updates.

Once created, ensure that the user credential is cached on the read-only domain controller.

If you need more information or guidance, then please contact technical support.
