I have a client/server network with Server 2003. I want to know what else I can do. The school has EVERYTHING like email accounts, policies like you cannot edit internet options, access control panel, deny access to local hard drive, change document directory etc..

How do I do it? Can I install a snap-in? Or another program? Where do I access some features? How do I customize internet explorer, home page, title bar etc? How do I manage the users email accounts so they can click outlook 2007 and have their gmail, aol, and yahoo accounts? Please help! Thanks
How do I manage desktops? Another thing I wanted answered.

The message that i’m getting during the installation of the email server software (hMailServer) is : The hMailServer setup has detected that one or several of the TCP/IP ports 25,110 and 143 are already in use. This indicates that there already is an email server running on this computer. If you plan to use any of these ports with hMailServer, the already existing server must be stopped.

My question is, how can i stop this service or server so i can install and use the hMailServer?

I’m running Windows 2000 Server.
Thanks
