When the time came to install the co-ax, we tried to hire our regular cabling contractor, a company with whom we'd done several successful cable installation jobs. But when we called the DoD to arrange for passes, we discovered that its security people would not authorize our guys to do the cabling. Apparently, due to some long-standing security regulation, all cabling had to be done by the DoD's own electrical department.

We had no choice, so we said OK. The DoD laid the cable, we installed the server, updated the stations with network cards, and configured the NetWare software. Everything was working like gangbusters.

At least we thought so. Several days after the DoD signed off, we got phone calls from a couple of data-entry clerks who couldn't see the server. We checked their systems, and everything looked cool. The only unusual thing was that they were both at the end of the network bus. Peculiar. We knew the hardware and software was working properly, and the distance from the server (on one end of the bus) to the technicians (on the other end) was well within Ethernet coaxial limits for distance and signal strength. We had to assume something had gone haywire in the actual physical installation. But what could it be?

Only one way to find out. "Charlie," our project manager, borrowed a tall stepladder and was halfway up to the drop-down ceiling when two armed security guards appeared and politely but firmly explained that any further attempt to access the overhead would be met with lethal force. Apparently there were concerns about bugs being planted in the overheads. Charlie climbed down in a hurry, but it was nearly half an hour before I could convince the security guards to put away the handcuffs.

Back at the home office, I called my boss, who placed several high-level phone calls to the DoD honchos. Two days later, a special security document was issued permitting our team to access the co-ax cabling, as long as those security guys kept their eyes on us.
