[K12OSN] HELP, everything's slowing down...

[K12LTSP]

Hi,

I restarted my server this morning, after the restart i can't get a 
display on the server anymore. Another thing, the clients boot so 
slow...really slow. i don't know if it's because of an update or what.

When logged in, i checked the system monitor. The memory usage is low 
but the CPU usage is 100% with only 5 users online.

The server is DELL PoweredgeSC1425 with Xeon PRocessor, 2GB Ram, 2 SCSI 
drives.

Please help.
