Users are identified in InfoWorks ICM by the user name with which they logged on to Windows. This user name is used to associate changes to data with the user that made them.
Because InfoWorks ICM needs to know who you are, it will not run unless you are logged in to the operating system.
If you are using an Oracle or SQL Server version of a workgroup database, you may also have to be added to the database as a user before you can access InfoWorks ICM data.
