Again, I'd VMWARE any sites you have out there as a precaution.
I'd also make sure you backup your LM DB's.
That solves your short term issues and gives you updated DB's you can use with any other LNS platform out there.
Next I'd monitor who picks this stuff up.
Finally, I'd look into the cryptkey, on both sides. Maybe they have a policy for this situation.
Anyway, I think somebody picks up the pieces here. Largely, the problems with Circon were not the software, or even most of the hardware.
Now you guys know when I visit why I tell you I don't like dealing with software on PC's and would much rather have devices like Touchscreens and web servers instead.
