I'm configuring my first Windows Server 2008 R2 Standard. This will be the one and only DC for this company and the only server. The server will be used for a file server, it will control the virus protection for the computers (currently 10 computers) in the company. The computers access to certain resources and drives will be controlled by the server but that is basically all it will be used for. The computers accessing the server will be Windows XP SP3 and 1 laptop running Windows 7. The reason for this post, is to find IT personnel that have had experience in this area and give me ideas or best pratices from experience to lock down this server. For all I know maybe it is locked down pretty much all the way now, so any knowledge from anyone would be helpful. Any questions will be answered that might help you help give me better insight.
Thanks in advance
