One of my customers has a Windows 2003 Small Business Server which at this point is basically the DC, DNS, Fileserver and Symantec Protection Manager.

I have disabled Exchange because I moved their mail to Google Apps.

The server is extremely sluggish when doing anything. It is most noticeable when a dialog box is open (say the System properties), and you try to change tabs. This is usually instant, but on this machine can take 3-5 seconds.

What additional services / packages can I uninstall from this machine knowing that it is only performing the above roles?

Will removing the "Small Business Server" package in Add / Remove Programs get rid of a few unnecessary things?

Any other thoughts?

P.S. I know Symantec Endpoint and the Protection Manager are hogs, but I have nothing to replace the solution with at the moment.

Thanks, Tom

UPDATE: I looked over the different performance metrics, but nothing stood out as a problem. One of my friends mentioned Symantec's log and temp files can get quite huge and slow things down, so I ran CCleaner on the machine and found close to 3 GB of Symantec "stuff."

Removed that and now the machine is MUCH better.

I am still unsure why the data just sitting there would cause such a slowdown. The drive is not even near full. The only thing I can imagine is that Symantec must have to run through this stuff now and then.
