Why can't I see network map in windows 7?

Clarifications

If it's not 2008 there could be issues with the way that it works compared to 7's newer Networking Protocols.

Is Windows 7 your local machine or is it Windows 2008?

Depending on the size of your network, creating a network map on a domain-based network can be inordinately slow, which is why it is disabled by default.

Could you post more information about your layout, connections etc. It makes it easier to find the problem.
Example,
Windows 7 connected to the server by Switch/Router or cross over cable.
Are you using your server as a backup?
Are you trying to connect Windows 7 to the internet through your server?
What exactly are you trying to do?
More information that you post the more we can help.

No i connect to the internet through an asa 5505 cisco firewall. I also have a wireless network but just for 2 laptops, they can't see the network mapping either. The only system that can retrieve a network map is the 2008 server. It is not used for backups, I have an external 1tb drive that I use to backup systems. This all started when i was curious to see how my network would map on the windows 7 desktop when I found out it was disabled. Its not mission critical or anything, just trying to learn new things whiile I study for MCSE. I like to see thing I don't already know in action instead of just reading it from a book.

What features and Roles are installed besides AD and DNS? Could be network policy settings on the 08 server. Did you start with making sure you can even ping the server? How about checking your net config on the workstation to make sure the setting are correct. Check your event logs too.

On my network the Win7 PCs only recognize and share with other Win7 machines on the network. If you only have one Win7 PC, you may not be able to "see" anything else except the internet connection.
