Cross Forest DFS namespace access Windows 2008

Background

Domain A we will call TestDomA.com
Domain B we will call TestDomB.com
Domain A is a 2008 Domain with domain based DFS 1 namespace as TestDomA\Common. We have separate Windows 2008 DC in this domain.
Domain B is a 2008 Domain with different domain based DFS. similar namespace in that domain like TestDomB\Common
Domain A has Two-Way Trust with Domain B and this is Forest Wide Authentication. This allows Domain B users to access resources within Domain A.

I want users in Domain B to be able to access DFS namespaces in Domain A. i.e. \\TestDomA\Common

I have configured the Share and Security permissions on the DFSRoots directory on the 1 DFS roots in Domain A to Read, List, Read & Execute for users in DomainB

I have configured DNS forwarder for DomainA in the DomainB DNS server.

I can able to ping the domain FQDN TestDomA.com from DomainB

From a Domain B workstation, i get the following when i type:

\\fox.net\                      =    I see Netlogon & Sysvol

\\IP ADDRESS\             =    I see Netlogon, Sysvol, & DFSShare, but when i double click the DFSShare i get the below error message ****

****Error Message Reads: "\\IP ADDRESS\Share is not accessible.

Network Path Not found. Error code: 0x80070035

I can open and navigate the Sysvol and Netlogon folders just fine.

Even I can browse normal share folders in Domain A from DomainB but not the DFS namespaces.

I want users in Domain B to be able to access DFS in Domain A.

Thanks.
