SYMPTOMS

Consider the following scenario:
  • The Active Directory domain NetBIOS name contains an ampersand (&) character in a Microsoft Exchange Server 2010 environment.
  • You try to install Exchange Server 2010 Service Pack 1 (SP1) on a server in the environment.
In this scenario, the installation fails. Additionally, you receive the following error message:
An error occurred while parsing EntityName. Line7, position 12.
