Whats in your software kit bag: Dell/Windows servers

Hi,

(Maybe this should be categorised under servers?)

I have a number of windows (2k3/2k/XP) machines ,all Dell, to admin, a number of which are not in the same location as I and thereford I have to travel to them.

I have my tools kit bag and the usual software CDs with me.

I am wondering what other “magic” software tools people have, either open source or payware, to get over any sort of problem. We all probably use similar tools, but I would be interested in hearing what other people use.

thanks in advance
