I'm curious, for those of you that have done Computer Management related jobs, like Network Administrator or Web Master or a position in Computer Repair. What's the worst network set-up you've walked into. What's the most convoluted network set-up you've seen somebody set-up.
At my current position, I walked into a mess. There were 3 DHCP server running on the network, and all three were spitting out the same IP Address schemes... They have a router set-up that hasn't been secured by new passwords, and the router isn't set up in a correct network layout.
The network has been added to and modified so many times over the years that they've lost passwords, license keys, and even a foundational knowledge of how the network runs. It's gotten so overwhelming I'm not sure where to even start.
So what have you network/computer gurus run into?
