I have just upgrade a 2000 domain with 2 2000 domain controllers, Exchange is installed one of the domain controllers. I moved fsmo roles to the exchange to upgrade it to windows 2003 it has Exchange2003 installed. Preformed the adprep/forest and domain then let system sync for a day, oh yea fully patched before upgrade. Upgraded to windows 2003 went smooth, then patched 2003, then install sp2 for exchange. All this went good which was good being it 3:00am. I got one problem thought I cannot get activesynce to work, I have a user trying to activsync his treo via work pc but he gets the exchange server does not have permission to synchronize with your current settings. We are not using ssl or forms based authentication. The Access Tab of ActiveSync properties under Exchange Virtual server are grayed out. Anyone seen this? Any help is appreciated. Thanks Bruce
