How to see other computer on Domain Network using Windows 7 client?

1. Open Advanced sharing settings by clicking the Start button , and then clicking Control Panel. In the search box, type network, click Network and Sharing Center, and then, in the left pane, click Change advanced sharing settings.

2. Click the chevron to expand your current network profile.

3. Click Turn on network discovery, and then click Save changes.  If you're prompted for an administrator password or confirmation, type the password or provide confirmation

Under Windows 7 you need to enable Sharing Profiles options to see and be seen with the default windows network browser.

To change these settings you need to go to:
Network Connection and Sharing Center --> then Advanced Sharing settings.  On that screen you would want to enable Network Discovery for the current active profile.  

Netwokr Discovery is already enabled and I still cannot see the network servers/clients.

They also have to have to have sharing enabled and most of all not be marked as in a 'public' network

Sharing is enabled, what do you mean "not be marked as in a public network"???

Also, if you are on a domain network mapping may be disabled, in network and sharing click the button that says "see full map" it will tell you if network mapping is enabled or disabled.

It only has "domain". Mapping is disabled. It says to enable it with group policy. Is there a way to do it without group policy??

I enabled Mapping and still nothing.

Is it this way on all Windows 7 clients or just this one station?

all windows 7 clients

all windows 7 clients cannnot see other windows 7 clients?  are you all members of the same workgroup?

All Windows 7 clients cannot see other computer on the network when you browse the network. All clients are part of a Domain. Windows XP clients CAN see all clients when browsing the network.

Today I can see all computers on the network when I browse the network.... isn't that strange?? Yesterday couldn't see any computers??
