Here is a quick tip on how to find out what host IPs are on your subnet using nmap. This is useful to find out what IPs are being used or just to know how many devices are connected to the subnet. # nmap -v -sP 192.168.1.0/24 You can replace the 192.168.1.0/24 address with whatever your IP and subnet is. Also, for a cleaner output that removes the lines that tell you an IP is not used, try the following: # nmap -v -sP 192.168.1.0/24 | grep -v "appears to be down"

There are some very good reasons why you might want to reinstall Microsoft Windows. Whether it is 2000, XP, or Vista, the registry can become corrupted or it can accumulate settings for programs long-since forgotten, leading to sluggish performance. Or you can find yourself with a stubborn Trojan Horse. The only way to be 100 percent sure that you have rid yourself of some particularly nasty viruses is to reload Windows. I have wanted to document the steps needed to properly reinstall Windows for a long time now. I always end up missing something after the reload and find myself scrambling to find IDs, passwords, configuration settings, or favorite Web sites lost in the reinstall. Be sure to set aside a large block of time to do the reinstall. Don't do it before a term paper is due or your business presentation slide show. A weekend is a good time. An OS reinstall is also a good time to decide to upgrade. If you want to upgrade to Vista, there are a lot of options available to you....

Once a print job is stuck in queue, nothing will print. Usually, you can navigate to the printer via the Control Panel, select the printer and cancel the document. But occasionally, a job will just sit there and refuse to die. If this happens, you can run the follow script to free it. Open notepad by going to Start, then Run and typing notepad and hit OK. Copy the following script: net stop spooler del %systemroot%\system32\spool\printers\*.shd del %systemroot%\system32\spool\printers\*.spl net start spooler ext, save this document as C:\DeletePrintJobs.cmd Once saved, navigate to Start, then Run and type or paste that filename in the run box. This will run the script from the command line automatically and shut down when finished. You should notice that all print queues are cleared and you can now resume printing. If you can't print after running this script, reboot your computer.
