We have Netware 6.5 SP8. About a month ago we started getting high processor utilization (in Monitor it goes up to around 50% - 55%) on the server every day around 11:00AM, and it stays high for about an hour, and then after an hour or so, it will drop back down to normal. During the high utilization time, the server really slows down to a crawl causing major user problems. I have no idea what is causing this; as far as I know nothing has changed on the server. I checked the backup system and nothing is running. I also checked the cron file and no cron jobs are running. In Monitor checking the Kernel, Busies Threads doesn't give much information either. It always shows something like "Server 34" or "Server 17". Is there any way to find out what is causing the high utilization?

Thanks....
