Had to deal with this one last night.
On Win2k Pro I just got an error about svchost.exe failing, and then my system would "wig out" on me. couldn't cut and paste and stuff.
I knew I should be running some firewall software, but just didn't get it quick enough. Shold have patched up too.
Oh well.
Interesting to note that Anti-virus software wouldn't have caught it anyway. At least Idon't think it would have.
Symantec virus scan didn't find it last night.

To be safe, everyone should re-format and install Linux.

Just curious. Does anyone know how to set up Zone Alarm on a webserver? I set it up once but it blocked traffic to the web site.

Thanks. Our external internet seems to be ok, but I have found 5 vulnerable systems on our internal lan.

Freepers are the best.

And if you are a network administrator and you let this worm get through, you should start looking for another job.

Hey, it's not that easy. One guy has over 100 Windows servers. He's installed the patch on all of them already buy not rebooted them all to have it take effect. Rebooting things ends services that may be mission critical. He's had about 2 weeks to take care of 100 servers and maybe 1000 workstations. Having done all that the network is still somewhat vulnerable to people docking inside the firewall who are infected. Really bad virus's are not simple to defeat. I therefore disagree with you assertion that the mere infection of a computer is a reasonable cause for termination of the sysadmin responsible for it.

I had the same thing on Win 2000, except the computer continued running normally with a few functions, like file transfers disabled. Win XP just kept rebooting anywhere from 5 seconds after starting, to 15 or so minutes. What a pain. I'm getting closer to using the ultimate windows patch.

SCREW THE BLASTER VIRUS!

I got this fricken thing on my home computer yesterday. Armed with more knowledge I am going home to kill the dragon and put it out of its freaking misery.

Luckily I am at work right now where my network's computers are safe and sound behind the glorious FIREWALL~!

Proud firewall admin watching the lava break against my defenses.

Yup. Woohoo! No Pasaran!

Of course, merely posting this will tell the Computer Gods that I am ripe for yet another Humbling Experience. Gotta go cut a chicken in the server room...

On the serious side, I've received reports that those who don't keep their patches current - you know who you are - may find application of this fix to Win2K boxes not patched to SP2 may find a little bluescreen awaiting them. What fun!

"Yeah, boss, that's just the new company wallpaper, trust me..."

...Gotta go cut a chicken in the server room...

What does that mean?

[dfwgator]

Even without the Microsoft patch, there is the little matter of the firewall, why even leave those ports open?

NOT THAT!!!!
I refuse to use some hippy OS.

[Billthedrill]

It means I must sacrifice to the Server Gods. People think these things run on electrons. No so. Evil spirits. Ask any SysAdmin...

[Jack Black]

what are peoples experience w/ Zone Alarm, Black Ice and other firewalls? I've been running ZA and like it. It is a little bit of a pain in the training period. I'm running the free version though, so who can complain. What are the advantages of the others? Anybody pay the $39 bux to ZA. I think I'm going to. I can afford it and it seems to work.

[FourPeas]

That's a bit harsh. All it takes is for an employee to take their laptop home, connect it to the net, get the virus and then bring the virus in-house.

Mr. FourPeas is in IT security for a Fortune 500 company. Hubby is now trying to cleanse a network at a remote location where no one seems to take it seriously. He actually is having to run a script to shut down various computers every ten minutes because the yahoos at the remote keep turning them back on even through they're known to be infected.

[dfwgator]

I will grant you that, fine. But still it should be someone's responsibility to ensure that those laptops are kept up to date with the latest Microsoft patches. This is not the first time something like this has happened. Seems to me these people are making pretty good money in this economy, they need to start being responsible for keeping their laptops up to date, or there needs to be someone on their case making sure it gets done. This costs companies way too much money to take lightly.

Which reminds me.... cut and paste is also disabled. As I do a 2 hour download of Win2000 sp4, I have visions of an OS that has more patches and hotfixes than some innertubes I used to own.

Thanks for the heads-up.
