Exchange 2007 Std on Server 2003 Std. I have poked a hole in the firewall for LDAP (389) and the request still times out. Is there a setting on the Exchange server that I need to enable? I have read that you don’t have to point to the Exchange server because it uses AD for LDAP queries. Do I have to enable access to a DC to make this work?
