I have recently started a new job and inherited a pretty sloppy network. My background is in Help Desk and I don't have much experience with the hardware side of support. I have a small office with about 20 PC's and two servers, and I need to label all my ports on two 16-port hubs. I am sure there is an easy way to do this without kicking people off the network for long periods of time but I don't know what it is. Please forgive my ignorance.
In such situation, I would rather prefer to tag the cables, rather than tagging all the ports. You need to decide a good naming convention for all your PCs and Servers, and then it's a pretty easy job then. Prepare the tags, and put them on the cables, at both the ends. A better way is to use a naming, so that you can find the PC name from the port naming. This way you will only have to tag the name on one side of the cable.
