Our SBS 2003 server is acting sluggish. It's SBS 2003 service pack 2 with 4GB of ram, Pentium D 3GHZ. What I am asking is, is there regular Maintenance I can do such as defrags, disk cleanup, etc...? I can manage maintenance on a desktop fine but I have never done it on a server and don't want mess anything up. The old IT company we had suggested not running disk cleanup but I am not sure why. Any help is appreciated.
