When trying to print to an ndps printer agent, a popup window came up and
said "Space to store the file waiting to be printed is not available on
the server". This popup window started after the print server abended.
The resolution is to shut down that printer agent and restarted and that
popup window went away. My question to you, is there a way to find out
which PAs have the similar problem or a single fix.

The print server is running on NW6.5 with sp3.
