Last night, I VPN'ed to the vpn concentrator at work from a computer at my house called (hostname) Zarathustra (just a standard windows VPN connection). After that, I was able to remote desktop thru the standard windows MSTSC (RDP) terminal services app to several computers at work. On one computer in particular, I have redirected RDP to accept incoming connections over port 22, so that I can remote desktop directly to that computer without VPN first (because that port 22 is allowed in past the work firewalls whereas 3389 is not).
When I got to work today, and I pinged the hostname Zarathustra, I found that it resolved to the IP of the VPN concentrator. The domain where my office workstation is located has DNS servers, but I'm pretty confident they do not allow dynamic updates (the whole org is static IP --- UHG!!). Anyhow, I am also pretty confident there are no WINS servers on the domain, so I'm left with, Netbios cache or something (I am skeptical that this was a leftover from a switch/router table). Any theories?
