my cups runneth badly

[Steve Strong <sstrong crwash org>]

so, I've had the printer set up and running and it's worked fine even
share it on the network with linux and win2k clients.  all of a sudden
(after installing the latest up2date stuff) lpq commands result in a
"service unavailable" error and the printer configuration tool finds no
device for printing.  i'm running cups and pointing my browser to
http://localhost:631 results in denied access.

Anybody know what's up?
