Currently I have this problem with two off our ndps brokers. They suddenly
stop responding for some reason with the following error on the console.

The Resource Management Service could not open the data file
ARCHIVE/NDPSDRVR.ZIP Error code 6. Make sure etc..

We are running NDPS in a Netware 5.1 cluster and so far it ran stable.

The only change we have made is moving off the replica's which contain
the PA Objects. A replica with the Broker and NDPS Manager object still
exist on that server.

Hope you can help.
