When you install Access, the Setup program automatically creates a workgroup information file for you. The workgroup is identified by the Workgroup ID (WID), a text string that the Setup program automatically creates based on your name and organization. Since this information can be determined by unauthorized users, you may want to create a new version of the workgroup information file, and with it a new WID, not so easily determined. Only someone who knows the WID will be able to create a copy of your workgroup information file and thus potentially gain access to Access's administrative accounts.
