Lately when I try to sign in on Ebay, they will not accept my password. I type in my secret question whenever I "forget" my password. They say they'll email me about it but never do. I emailed tech support and they just give me the run around. I also tried to re-register. First with my normal info but they wouldn't accept my password. Then I try again with a new password but they say that my ID is already taken. You would think that with my name and address being the same that I'm the same person and not a strange coincidence. Ebay is of no help but I'm hoping someone here has the answer because. I may need to re-register with a new ID but I shouldn't have to.

It's a little less than that, it's from Dell and it's currently $800 off for me. It would be fully decked out with everything I could possibly need including a 4 year warrenty, etc.

Worth it or not (the deal can be seen on slickdeals.net frontpage)

Okay, I made me one of them there "perfect servers" using Ubuntu 7.10 and I need to have the DNS working on the thing.
Now, my bind is chrooted to /var/lib/named.
I have my nodes null and random up in there.
I have all the /etc/default/bind9 file configured to point to the jail.
I have the log files working.
I have resolv.conf.options set to point to a known working name server.
I HAVE NO ZONES except the nulls,
In short the thing would appear to be configured right.
There is little or nothing to get in the way.


But it DOES NOT RESOLVE. Not no how not no way.

Anybody out there think they might know what's up? Port 53 seems to be passing traffic just fine,...

I am open to wild ideas here.

One think to help along the way... The thing was okay, when it lived at a different IP address, but now that it is where it is supposed to be, nada.

Any latent configuration files that might giving me lip?

I just bought a Compaq Presario V3630TU windows XP notebook. I cant hibrenate or put it in standby. When ever i press the sleep button, a blue screen will appear with lots of words. Before i can read them, the notebook will restart. Can anyone help. I ask the shop which bought it, and they suggest me to format it, they indicate that is nothing to do with the sofware but the notebook itself. They also say if that dosent work, i have to bring it to the HP Compaq service center. But can anyone suggest any other solution.?

I've used Sunbelt-Kerio firewall on my Windows XP system. Now, I am using Windows Vista on my new notebook. Unfortunately, Sunbelt-Kerio firewall does not support Windows Vista. I've tried to install ZoneAlarm Free Edition 7.1.0 but my computer crashed during the installation process. Any recommendations on a free firewall which supports Windows Vista.

VHP is so different from Millenium and Windows 98 and even though I found this once, I haven't been able to find it since then. Can someone walk me through, step-by-step, how to go in and defrag under this program please?

I really like VHP but I don't think it is user friendly and that bugs me when someone makes a program more difficult than it needs to be.

Appreciate any help anyone can give me.

My wireless Internet connection used to be super fast. However, it has been extremely slow lately. Websites take about half a minute to load and need to be refreshed a lot, the download speed drastically decreased (around 20 kb/s), and I often get timed-out or disconnected.

I have tried using some programs (TweakMaster and WinSockFix) to help boost my Internet speed but they did not help at all. I have also tried repairing my wireless Internet connection, but that did not help either.

What could be the cause of this, and is there any way to fix the problem?

Thank you very much.

I know that it loops 3 times, but I can't explain why. I know it has something to do with the " i *=5 ". Can someone please explain. Thanks.
