I'm in the process of improving my linux/unix skills, administrative and in general, and working on getting a feel for 2003 administration ... I'm currently building a dual pentium II machine, 333mhz-450mhz not sure yet, with dual 18.2gb SCSI drives and 256-512mb of SDRAM ... I'm looking to broaden my skillset, improve my employability and raise my demandable salary. I'm currently heavy on application development skills, particularly Microsoft web and database technologies, with a lot of ColdFusion and a fair amount of java experience. faced with relatively low-end technology, and coming from a microsoft-heavy background, would it seem to make more sense to turn the dual machine into a linux or a windows 2003 server? it's going to provide DHCP, DNS, domain authentication, fileserver services, FTP, possible proxy, etc. etc. I already run a linux firewall/router on the network, but I'd like to strip it down to be JUST a firewall/router and not provide the other services that the new device I mentioned I will be configuring for.
