Remember working MSDOS 3.11 on an IB PCjr, then WFW 3.11, then fighting the crashing Win95. About the time of OSR2 I switched to NT4 and never looked back :)
Oh yea, Linux (from scratch) since 2.0 kernels, FreeBSD, and OpenBSD too since we're talking OS experience.
Cisco and 3Com switching, Ironport anti-Spam, Tippingpoint IPS are my network abilities.
Programming you ask? C++, C#, NT CMD, and perl are my primary languages. I also do VBScript/VBA, and a tad of PS.
