Server is very sluggish due to various processes in task manager using CPU

Not sure what happened here.  We have a windows 2003 SBS which has been running very well.  We downloaded some windows updates and now a bunch of processes are acting very eradic jumping from 0 to 50% of the CPU usage.  It is causing the users to experience latency on exchange via outlook.  It has brought the server ot a crawl.  can anyone provide any assistance on how to rectify this?

The problem just went away on its own.  Just sort of fixed itself.  It was strange.  Many processes were running randomly and then just stopped.

You can try uninstalling the updates. You did not provide much information, but doing that may help.
Good luck.

What processes are proving the spikes? Do you know what each of the processes do?

On Server 2003 SBS you do have Exchange, Active Directory, and Reporting and Monitoring running all together. Over time this machine may get overloaded. That could be your issue.

One of the processes is SYSTEM and it jumps from 0 to 55 than back to 0 then back to 45 - it is random, but it definitely causing the latency spikes

What kind of specs do you have on this system? On a Small Business Server you'll have the following processes running: Exchange Server (regardless of if you're using it), System and Error Reporting (regardless of if you're using it), IIS (regardless of if you're using it), SQL if it's a Premium server, not to mention Active Directory, DNS, WINS, hopefully DHCP and any other software you have installed.

Bare minimum RAM I recommend on any SBS is 2GB, I always sell them with 4GB to be safe.
