The dcelocal/var/dfs/admin.bos file on the local disk of each File Server machine contains the names of users who are allowed to issue bos commands on that machine. All users can list the contents of the file with the bos lsadmin command; only administrative users can edit the contents of the file with the bos addadmin and bos rmadmin commands. Because the admin.bos file is a binary file, you cannot edit it directly; you must use the appropriate bos commands.
