I'm trying to setup GALSync and I created the MA for the forest my MIM server lives in, but cannot get it to work with the Trusted Forest, fails with error code 1355. If I replace Forest Name and Domain with an IP of a Domain Controller in that forest, it works no problem. This screams DNS issue to me, but I can't create any sort of DNS failure, can ping, reverse lookup, do nslookup for srv records.
I came across an old thread that mentioned using MIISDCInfo from the MIIS Reskit, but I can't find that. Is it still available or anything like it available for FIM or MIM?
