Can't browse computers on different subnets

Microsoft Windows server 2008 r2 standar...

Specs: Server 2008
We have been running with 4 Windows Server 2003 Domain Controllers and 4 different subnets for the past 5 years. In all that time, we have always been able to browse out from "My Network" and view all the computers across all subnets. At the end of January, 2010, we upgraded our Server 2003 Domain Controllers to Server 2008 Domain Controllers. Ever since the switchover, we can no longer BROWSE to clients on different subnets. Does anyone know of any settings that may need to be configured on Server 2008 to allow this?

To clarify, we CAN type the IP address or UNC name of the client in the address bar and view it without problems but some of our software requires you to be able to actually browse out to the data location and doesn't give you the ability to type a location in. Mapping network drives on the computers to some of these data locations isn't an option due to security but we are having to do this as a temporary fix.

Also, we have all of our routing tables set up on our Cisco switches and we double checked that nothing had been changed at that level so there is nothing blocking traffic between subnets. The only thing that has changed is that we went from Server 2003 to Server 2008.

Thanks for any help y'all are able to give!

Check, whether the computer browser service at the 2008 server is running.
When installing a new windows 2008 server or upgrading an existing 2003 server to 2008, the Computer Browser Service is disabled by default.

This sounds like a DNS issue. I would suggest you look through all host records in your DNS that are associated with all servers and ensure they're correct.
