We were trying to integrate our program with our collaborator's program. So I cannot replicate the error right now. I remember that while trying to connect from LabVIEW 7.0 DSS to LabVIEW 7.1 DSS, it gave a connection error saying that the versions were incompatible. Then we tried connecting computers which had the same version (LabVIEW 7.1) and didn't run into any connection problems.
I'll add to this post when I am able to regenerate the error, but it might not be for a week or two.
