PARCdisplay Service has limitations worth considering:
The service works for PARCview-type files only.
The service uses a single user account for access to all folders and files, so all users for a particular service instance will have the same access rights to all of the folders/files.
The service can only be run as a local admin on the server.
Users cannot create or modify PARCgraphics Designer files over the service.
The DSN field in Site Select will not have access to a UDL file in a network location, so the UDL file needs to be on the client.
The service does not support shortcuts.
