--------------( the above is an advertisement )-------------- 1) A Closer LookIn the current InformationWeek.Com column, you'll get updates on three important and interesting technologies and trends: You'll see my new powerline networking recommendations, you'll read about a $400 PC I recently got that easily matches a box I paid almost $2000 for, just two years ago; and learn of a new GPS adventure involving (for real!) a shipwreck and a desert island! The last item was definitely one of the highlights of my recent vacation. <g> So, if any of those topics interests you--- inexpensive PCs, networking over ordinary electrical wiring (no drilling, no new cables!), or GPS--- click on over to http://www.informationweek.com/story/showArticle.jhtml?articleID=14100041 for the updated info, and then join in the associated discussion to share info on those--- or any--- topics with your fellow readers.

It's an outgrowth of the basic PnP (Plug and Play) hardware standard from the mid-1990's, extended to networked devices. It's not an inherently bad thing, but there's very little that actually uses uPnP yet. And it can cause trouble:
The unguarded port that the Symantec site uncovered is the one meant for use by uPnP-using devices to communicate between and among themselves. (See http://www.upnp.org/ ) But it serves no purpose if you have no uPnP devices (and most of us don't.) Plus, Microsoft's uPnP implementation originally had some security holes (surprise, surprise!), which left many machines potentially vulnerable. The holes have been long patched (see http://www.microsoft.com/technet/security/bulletin/MS01-059.asp from 2001, for example) but the port is still there, mostly unused, and a potential target for crackers. uPnP may become more important in the future, so it's not something you want to rip out of your OS. Rather, it makes more sense to disable the uPnP services until and unless you need them. This lets your firewall close--- and preferably stealth--- the port, so crackers can't break in, and in fact can't even see that there's a PC online if they look for that port. The easiest way to control uPnP is with Steve Gibson's tiny, free "UnPlug n' Pray" utility, which I've installed on all my PCs. When you run it, it tells you if uPnP is active; and if it is, offers to disable it nondestructively. Or, if uPnP is disabled, the utility lets you turn it back on with a click. This way, you can turn off uPnP now, if you don't need it, and yet reactive it easily on demand at any point in the future. Grab a copy by going to http://grc.com/unpnp/unpnp.htm , or to http://grc.com/ and check out all the stuff there. As we mentioned last week ( http://www.langa.com/newsletters/2003/2003-09-04.htm ), it's a gold mine! BTW: The Symantec port-scan is good; it's actually one of several excellent, free, online scanning services than can harmlessly probe your defenses and alert you to any weaknesses.

As usual, many of you had *great* additional information and suggestions. Here's a sampling:

Thanks, Bronson! The "Thunderbird" nomenclature may be unfamiliar to those who haven't been following the Mozilla project: Most of today's major browsers trace their ancestry back to the ancient “Mosaic” browser project from the early 1990's. When Mosaic first started to become a commercial product, it was beefed up and made into a "killer" browser that the developers hoped would slay the competition. To embody their hopes, they named the new browser “Mozilla” after (believe it or not) Mosaic + Godzilla. (That's where the fire-breathing dragon logo comes from!) "Mozilla" eventually became Netscape, which later got eaten by AOL, which then released the Netscape browser source code to the Open Source community, which used it to produce a new, reborn Mozilla browser. AOL/Netscape then used that reborn Mozilla code as the core of a new generation of "Netscape" branded browsers: In other words, Netscape browsers are today really just AOL-modified cousins of the Open Source Mozilla browser. (Whew! That's a practically Biblical series of "begats...") Internet Explorer also is a descendant of Mosaic/Mozilla: A separate company arising from Mosaic/Mozilla was called "Spyglass," and that source code was licensed by Microsoft and used as the basis for the first versions of IE. Today's Mozilla browser ( http://www.mozilla.org/ ) is quite good. It has all the essential stuff that the "Netscape" version has, without the extra, um, baggage layered in by AOL. The next major version of the Mozilla browser is being called "Firebird." ( http://www.mozilla.org/products/firebird/ ) It's currently in slow development, at version 0.6. Now back to Bronson's point: A different group within Mozilla.Org is tackling email as a separate item, seeking to produce a lean, clean and stand-alone(!) mail client that can work with Mozilla or other browsers, but that isn't actually part of a browser package. They've played off the "Firebird" theme by calling the new stand-alone mail client "Thunderbird." You can read about it at http://www.mozilla.org/projects/thunderbird It does look good, and is definitely one to watch! Click to email this item to a

First, turning off System Restore on all drives/partitions in your system should automatically delete all stored "restore points" on your system, and free up a lot of space--- at least 200 MB, and usually much more (like the 1GB+ on Mick's system). But after System Restore is disabled, you also can manually remove any "_Restore" folders if you need to. See this page for combined information on enabling/disabling System Restore in ME and XP: http://www.pchell.com/virus/systemrestore.shtml Second, any "bak" file should be able to be removed without causing trouble; same as with "tmp" or "temp" files. Plus, if you have good backups, you can freely delete ANY file you suspect is bogus or unneeded, because if it turns out that you do need the file, you can simply restore it from the backup. So, if I were you, because bak files are usually expendable anyway, and because you do have backups in the event that this one turns out to be needed, I'd whack the bak file without qualms. But if you want to dig deeper, there's lots more available on propstor: Click to email this item to a

--------------( the above is an advertisement )-------------- 9) "In Situ" Reinstalls
Usually, this is simply a matter of popping in the setup CD and laying in a new install right on top of the old one, using exactly the same setup location, parameters, etc. In some cases, you may be asked if you want to "repair" the current installation; that may be worth a try, as a first step. But even a full reinstall on top of an existing setup usually will retain your data files, and--- depending on the exact circumstances--- may also leave alone your user preferences, installed apps, etc. But there are three potential problems: First, depending on what was wrong with the setup you're trying to fix, an in-place reinstall may simply inherit the same problem--- there's no guarantee that the reinstall will fix what's wrong. This kind of reinstall can even create new problems by undoing or rolling back patches and updates you've installed, which may or may not be what you want to happen. Second, especially with Win2K and XP, there's a nontrivial chance that you will lose some data. The full explanation, and workarounds, are contained in these detailed Knowledgebase articles: How to Perform an In-Place Upgrade (Reinstallation) of Windows XP: You May Lose Data or Program Settings After Reinstalling, Repairing, or
Upgrading Windows XP: Third, note that a reinstall from a normal setup CD is not the same as a restore from a factory "recovery" or "image" CD: A reinstall works from a normal setup disk, and rebuilds the OS piece by piece. Files outside the OS often aren't touched at all. In contrast, a restore from a recovery disk may put everything on the hard drive back the way it was when you first got the system, totally wiping out your entire current setup, including user files. That's NOT what you want if you're trying to preserve things. There's another option for older versions of Windows--- an easy way to do a total reinstall *without* reformatting and without touching your data files. It's explained in "Fred's Super-Fast, No-Reformat Fix for Broken Win9x Installations" here: http://www.browsertune.com/bt2kfast/recovery2.htm But in all cases, MAKE A BACKUP FIRST so you'll be protected, just in case!
