fix

The risk of placing all your NDPS Printer Agents (PAs) or a great amount of them on a single NDPS Manager is that if you have a problem that cannot be quickly resolved a rather large portion of your users will be unable to print until you find another server to migrate the manager to (assuming you are able to do this). If planning to run a higher number of PAs on an NDPS Manager, ensure that you have an alternate server and/or hardware platform of equal or better performance to move the NDPS Manager to.

Note that only one NDPS Manager can run on any given server. You cannot temporarily move an NDPS Manager to a server which is already running some other NDPS Manager. For a two-server shop it may be more beneficial to have 200 printer agents on a single NDPS Manager instead of splitting the printers into two NDPS Managers of 100 PAs each, then the single NDPS Manager could be moved from one server to the other as necessary.

Cases of over 1000 PAs on a single NDPS Manager have been known to exist on NetWare 5.1 on PIII-class hardware in clustered environments. Unless you are in a clustered environment where fail-over tolerance is high Novell recommends you should not place more than 200 to 300 PAs on one NDPS Manager. If you must place a larger number (400+) of PAs on a single NDPS Manager make sure your LAN card is intelligent (CPU off-loading).
