Hi all, having this problem with MS Exchange2k - it is SBS so it acts as DNS itself I have googled for a while and it seems to me that my AD settings must be wrong .... but they seems OK to me - both forward and reverse lookup zones are OK with autoupdate enabled. Using dcdiag and netdiag shows no problem, using policytest from Exchange CD shows the rights correctly (after running setup /preparedomain from Exchange installation CD) .... I am lost Thanx Harry
