Domain DNS issue?

Hi,

I have 2 domains I am trying to get MRC to work with.  I have Domain 1 which is our primary domain and where the MRC installs live.  I have Domain 2 which is where some of the users we need to support are at.  Domain 1 has a one way trust to Domain 2.  Domain 1 DNS has forward look up zone and can see Domain 2 hosts and IPs.  I can ping devices via IP only on Domain 2 from Domain 1.  On my test machine which is located on Domain 1, I have added Domain 1 as preferred DNS and Domain 2 as secondary DNS, and I tried swapping the 2 around with no success.  Has anyone else run into this issue before and have you resolved it?
