My cable modem has both a USB and an Ethernet port - can I connect two computers?

I have a cable modem with USB and ETHERNET connections, and I've connected a computer to each. Both seem to work, and I get different IP's on each machine. But when I talked to the cable company they told me it's not re commanded and that it can even seriously harm the modem! Sometimes the machines get the same default gateway address and when this happens some things don't work. Is all this logical? Is it allowed to have 2 IPs?

I'm a little suspicious about the threat of "serious harm" to your modem, and I actually expect the gateway address to be the same.

But whether or not it should work, or whether or not you're allowed to have two IP addresses ... that's up to your ISP.

Why can't I send email from all my accounts?

For various reasons I have two email accounts with different ISP's ... Comcast and Verizon. For some reason when I'm at home, where Verizon provides my connectivity, I can't send email using my Comcast account. Yet when I'm at work or elsewhere, I can send using either. Why? And what can I do?

Welcome to another casualty in the war against spam. ISPs are starting to use various techniques to limit the use of their mail servers to only their clients.

Depending on what your ISP allows, you may be able to reconfigure. On the other hand, while it wasn't the last straw, it's one additional reason that my former ISP is my former ISP.

How can I tell what's taking up so much disk space?

My hard disk keeps filling up. I know I can do things like delete temporary files, the Internet Explorer cache and the like, but it seems like there's something else taking more space than it should. Is there a way to find out?

Absolutely. In fact, slowly losing disk space is one of those things that's not only annoying, but can often be a sign of a problem such as a virus or spyware.

Fortunately there are free tools available to help figure it out.

This is one of those little-understood tools that's already on your Windows XP machine that can often help when you certain types of problems with Windows:

What is the System File Checker, and how do I run it?

Windows XP works very hard to maintain the integrity of the system files on your machine. If you try to replace one of the "protected" files, you may get an informative message that the operating system has put the old, approved, version back. Not all files are under system file protection, and even for those that are, there are ways around it. Occasionally system files become corrupt.

Enter the SFC, the System File Checker.

*** Interesting Sites and Useful Resources


Lockergnome is a technically oriented site that covers a lot of territory. To call it a "site" is an understatement - it's a small empire of technical newsletters, publications and support sites.

I'd invite you to view the entire site, of course, but I'd like to direct you to one specific resource, and another place to get help and get your questions answers: the Lockergnome Forums at http://help.lockergnome.com/. There are a lot of smart folks out there who're ready and willing to help address or comment on most common problems.

You may already know that my weekly podcast is fed on Chris Pirillo's weekly streaming internet show, http://thechrispirilloshow.com/, and that show's podcast. Several of my video tips were developed specifically for Lockergnome's Windows newsletter as well.

The Daily Wav

Every day a short, funny, audio clip from popular media such as movies, TV shows and more. The Daily Wav has been around for 11 years now, and has a vast archive of clips from recent years, organized by date as well as show name. There aren't many sites that I make a proactive effort to visit every day, but this is definitely one of them.

*** Leo's Thoughts and Comments

One reason I've moved my comments further down in the newsletter is to allow myself a little more freedom ... I didn't want to get in the way of the technical content, but I did feel myself wanting the freedom to say a little more. Hopefully it'll be interesting to someone besides myself.

Last week I'd asked for any ideas on why folks might post questions on my web site articles that are clearly answered in the articles ... even posting the very title of the article as a comment. (It happened again this morning. Twice.)

I can only assume you are all are as bemused as I am, since I got not one idea.

Oh well. For now I'll just chalk it up to "stuff happens" and not make any further changes.

As always, if you have a comment on the site, this newsletter, or how they can be more helpful, less confusing, or whatever, by all means drop me an email at leo <at> ask-leo.com. I read every email I get, and while I can't reply to absolutely everyone, I do try to prioritize responding to folks who've taken the time to subscribe to my newsletter.

And I definitely appreciate any feedback you might have.

My article a couple of weeks ago regarding when you should, and should not, use the "This is Spam" button Why shouldn't I use the "Report Spam" or "Junk" button? - http://ask-leo.com/why_shouldnt_i_use_the_report_spam_or_junk_button.html) generated some interesting discussion in the article's comments.

The irony of it all is that the Corgi-L mailing list, of which I am a moderator, is currently having some massive problems delivering to AOL subscribers. Exactly the kind of problems that would result from a few too many people hitting the "This is Spam" button when they shouldn't.

I definitely understand people's frustration with spam. I get a ton of it. But I also understand that the "cure" is sometimes worse than the disease, especially when the cure is misused.

Sadly, I also don't know the answer. I wish I did.

*** Newsletter Administration Department

Do you have a question? A comment, perhaps? Newsletter subscribers can drop me a line at leo <at> ask-leo.com. (I only give that email address to newsletter subscribers, so I'll know it's from one of my loyal readers.) If you like, you can make sure you get past any spam filters by simply posting your question or comment using the Ask Leo! question form: http://ask-leo.com/askleo.html.

I'll be honest: I'll try to respond, but I get a lot of questions every day - I'm currently quite backlogged. I simply cannot answer absolutely every one. Rest assured, though, that even if you don't hear from me directly, I read every email I get.
