I make the same problem, but when I search for resolution and I see that, my domain name is not equal for all network, I have 1 NT Server is the PDC and the e-smith is the gateway the problem is (for distraction) the domain name in the NT is not the same for e-smith, not a big diference but.... (domain.country in the NT, and home.domain.country on the e-smith). Maybe this help you.
