One-Half Trust working

if you peruse the other questions i have asked regarding the use of LMHOST and setting trusts via a WAN, i am making progress. If fact, i have been able to establish a one-way trust from my District Office server to all three remote sites.

I havebeen successful in establishing a two way trust between one of the three. I have repeated the steps at the other two sites, but for the life of me cannot get the second half of the two-way to work.

Any thoughts?
