Hello: I am doing some testing with a managed e-mail provider. They will receive my e-mail and then send it to me. As part of the service they can do an LDAP lookup against my AD. I have a front end Exchange server in my DMZ. My thinking was to have the LDAP queries go there but my front end Exchange server is not a Domain Controller. Does anyone know how I could get my front end Exchange server to do LDAP queries? Harrison
