I created a group policy to restrict a particular group of users from web email, such as yahoo, aol, hotmail.  The policy somehow trickled to other users and computers.
I removed and deleted the policy but alot of my users are still restricted from web email, few computers allow web email access but most of them restrict it.  How can I undo this?

Policy is done through Organisational Units (OU) in Active Directory

If you want to activate a special set of policies to certain group of computers or users, you should create a new OU for this group, and move the certain group of user or computers objects to this OU, and create the policy on this new OU

5. EXIT

I do not understand why very few machines will allow web email but the majority will not.  I want web email allowed now and cannot figure how to reverse the restriction other than deleting the group policy which I did.

Thank you

Well, how did you deny the web email access? AFAIK, there's no native GPO setting to prevent access to certain web sites; did you use a custom template file?

Maybe it's not a policy that's doing the restrictions ???

Cleaning your computer  - and protecting it in the future -  can't be answered with one issue.

As you can see in my url below there are at least 7 different issues, where you should decide 1 of each, or else you does'nt protect your computer at all.

The reason is, that the many different programs not always protects against each other, and each of them does'nt protect equally.

It's very important, that you study all of these issues in my knowledgebase (some of them are freeware):
http://www.tryware.dk/English/Knowledgebase/HowToProtectYourComputer.html

BTW: I'm using the Trend Micro virus-suite, and SoftScan , and haven't got any of my servers or computers infected since 1999.

The policy was created in group policy Active Directory windows 2000 server.  Created a new policy and went to user configuration - windows settings  - internet explorer maintenance - security - security zones and content ratings -  security zones and privacy - modify settings - restricted sites - added the   aol.com   hotmail.com  yahoo.com  - and applied this  group policy to an OU.  The problem is the policy applied across the network to all OU's even though it was only applied to Middle school students.  How do I get rid of it?  I have removed the policy from the ou, but it is still restricting users across the network.

Never mind - I fixed the problem.  I created another gp and applied to all workstations across the network and then enforced the group policy refresh. It is now working.
