|  | Creating a Uniqueness Database File Mapping Unique IDs
The first section of a UDF assigns the unique IDs to the appropriate answer file section headers. The unique IDs are listed under the [UniqueIDs] section heading: [UniqueIDs] ComputerID1=TapiLocation, Network ComputerID2=UserData The information on the left side of the equal sign is the unique ID, which can contain any character except an asterisk (*), space, comma, or equal sign (=). The information on the right side of the equal sign is a list of sections that will be merged with the answer file sections for the associated computer or computers that correspond to that unique ID. These section headers must exactly match the names of the corresponding sections in the answer file, or the settings in the answer file will not be replaced.
