A loosely-coupled computer system certains global resources and is made up of stand-alone systems connected by a data link. Each stand-alone system includes a global identifier list which contains identifiers for global resources and the locations of those resources. The global identifier list in each system is identical to those on other systems. Each system further includes a global identifier list maintenance system, an outbound global resource system, an inbound global resource system, and a communications system. When a request for a global resource is made in a stand-alone system, the outbound global resource system determines whether the resource is local or remote. If the resource is remote, the outbound global resource system makes a resource access message and sends it via the communications system to the remote system where the resource is located. The inbound global resource system on the remote system responds to the resource access message by performing the access and providing a return message to the local system. The global identifier list maintenance system keeps the identifier list identical in all stand-alone systems. Global resources disclosed include global aliases for mailboxes, global file access, and global user and group name lists.
