Hello, Currently we have Windows 2003 SP1, Exchange 2003 SP2. Ditribution list is Global and Domain local group. We also have nested DL within the DL. We are having problem with users sending email to the DL that reciepients did not received the email. We had been assigned the expansion server to the DL instead of any server in the org to fix the issue. We would like to change to Universal Group for these DL. Do you have any scripting avaialbe to do the job to convert from Domain, Global to Univesal group? Can we fix the nested dl with the script as well or have to do it manually with expansion server? Your assistance is much appreciate. We estimate to have about 3000 DL on AD. Regards, Mau Nguyen
