So this week, my email server which is also the domain controller has failed twice. It's a weird little problem that I've never seen before. Has something to do with the network card, but it's all on the software side. Rebooting fixes it.

I've finally decided that Windows 2003 Server's Clustering Service may be the solution to my redundancy needs. The problem though is that I've got to get the second server set up first and move over all of the server tasks to it, then reinstall on the first machine and tell it to be a cluster with the first. It sounds easy, until I think about how much work that'll be moving over all of the Exchange data and everything else. I'm not looking forward to this.
