We are looking after a school network and the print server which is also the backup domain controller is having problems with high CPU usage. The two offending processes are spoolsv.exe and SYSTEM. We have recently rebooted all the servers and for 2 days the print server was running normal untill this morning when it was noticed that the cpu usage was back to 100%. We have found 2 computers that also have a high spoolsv.exe and when they have been terminated the CPU usage has decreased. We have also noticed that in the morning the usage is low then througout the day the CPU usage increase

Monitor volume of print jobs being sent throughout the day.
Also check the latest SP and hotfixes are applied on the server.

Print jobs vary, and the problem is intermittant. It appears to happen at least once a week, and on different days.

The server has the latest SP and available updates.

One thing to note is that unplugging the network cable from the server immediately resolves the issue. Reconnecing the network cable, and the processor maxes out.

I have found that network computers are opening sessions to spoolss on the server and keeping them open all day, even after the user has logged out. Some computers are opening 3 sessions. Because these maintain an idle time of 00:00:00 I can see they are constantly connected to the server, and each one accounts for about 5% cpu usage, which is why it gets to 100%. If those computers are reset, the problem dissappears, until they come on again and are logged in.

Replaced the printer drivers completely. By uninstalling and forcing reinstall over the top and then a reboot fixed the problem. It was either the HP or the Kyocera drivers. I'm pretty sure it was the HP.
