I was troubleshooting why an upgrade from 10Mb Cards to 100Mb cards wasn’t working for a group of users. Tracing the lines and come to find out the existing lines were Cat-3…. that suddenly got splice in to a 50-pair telco bundle at a 66 block. Worked perfectly fine for 10Mb, not so much for anything faster.

We had a section of comptuers that would not properly image. Come to find out that there were actual cat 3 cables mixed in randomly across the floor. That was the year that I bought several hundred new ethernet cables and we replaced every last one of them to be sure.
