Use this dialog box to specify a generic account that should be given access to the package on distribution points. Generic access accounts are mapped to actual user or group accounts specific to the network operating systems of individual distribution points. You can create your own package access accounts in addition to or in place of generic access accounts to gain further control over access to package source files on distribution points.
Caution Do not remove the generic Administrators account without specifying one or more package access accounts that provide the SMS Service account full control on all necessary distribution points. Failure to do so will result in the Distribution Manager component being unable to install, update, or remove the package on distribution points.
