Deny access to all computers of a network...

Someone here is wandering how this person denied everyone's permission to accessing this specific computer on the network, the method of this or the method to stop this would be deeply appreciated.
The OS is Windows 2000, the networking program is called "My Network Places". I have already tried canceling the share then making a new one with Full Control enabled to everyone, but the error message keeps coming up.

Thanks in advance.

Check the user permissions, see who has administrative rights. Then check the other users to make sure they weren't assigned to a new group. Hope this helps, enjoy

disabling My Network Places comes from security policies set by that
person or the administrator.

Sorry, but I'm going to need the steps to do that.

1 press start
2 settings
3 network and dial-connections

this is for 2000 professional version... im pretty sure its the same

I found the exact steps to fixing my problem, I first had to go to My Computer. There, I right clicked C:\ and selected "Sharing..." then selected the "Security" tab on the top of the window. In Security I clicked the "Advanced" button near the bottom. There, the permissions to "Everyone" was Denied. Therefore, I highlighted Everyone and clicked View/Edit and everything under Permissions was checked as Deny, all one had to do was just check all the permissions to Allow then click Ok then Apply on the next window. Thanks for your help.

well that was pretty lame of whoever set that up

glad you fixed it though! problems like this are hard to help out with,
because of only being able to go off of your descriptions. If I was sitting
at your pc, that may have been one of the first things I notice just for it
being different.
