Kyocera TA550ci
Fiery System 9e Rel2
All updates applied to server

This Fiery randomly gives the 503 error both pulling up the web page and logging into the System software from the copier control panel. Saw something about DNS in another post and have checked but nothing has changed on the network and Fiery has correct DNS info.

Sometimes 1 shut down brings the server back online but sometimes it takes 3 or 4 shut downs.
