If you can't block it by the domain name since the IP will change sometimes place a fixed record in your DNS zone pointing it at 127.0.0.1

Gives me an idea, not sure if it will work. If blocking login.yahoo.com will work, you could also use the Hosts file to point the computer to 127.0.01 when it tries to go t login.yahoo.com.

Yes, dead right..... but Angelic has an AD domain so all he has to do is add it to the AD zone and all computers will be similarly affected and the users can't change it.... Some may be able to get to the hosts file..... ;)

[Edit]

Neg:

Try that all again tomorrow..... They'll be different.....

Find the "choke" point.... it's login.yahoo.com.... Block that and you block all dangerous yahoo functions.... It's a beautiful thing..... ;)

Didn't think of that. I see now the other person's idea was more suited for the problem. My apologies.

The other person was me.... ;)

Don't apologize..... you were right.... I happen to have a better idea of Angelic's system than many do because we have talked about it a lot.....

Don't worry, you did good.....

Cool beans! Good luck with it all!

While on the subject.... the easy answers are always right in front of you if you look. Never thought of redirceting login.yahoo.com to 127.0.0.1. Shoot. But I wanted to interject. I know websense get's mentioned alot and I have been looking at it as a replacement to surfcontrol. It claims to have facility to manage IM usage. Anyone seen this first hand?

Some people use it to communicate with peers. Such as myself. I am hesitant to block all of them totally.

(And if all else fails, use a LART on those users that persist on using Yahoo. ;))
