Not yet, ive been having some raid issues where one of my three hard drives drops it's connection, i then have to leave it for 24 hours to rebuild, which is very annoying.
I have, however, just got my exchange VM server running over my domain name and connected to my iphone, everything is syching perfectly.
Next up VPN, FTP, Webserver, and maybe term serv if i can be arsed. then ill be routing everything through my ISA server and getting some of the guys at work to do some penetration (oo'er) testing. After that it's time to break it all and learn how to fix things.
Yes im a geek, but this helps me in my job.
