Hi Group, My firm want to run our Exchange 5.5 on cluster, we want to install w2k adv. in the cluster an then install exchange 5.5 because we don't run AD right now. Is it possible to run Exchange 5.5 on w2k adv. and will it give us problems ? I would like to hear from someone that has the environment and what problems there has been. Also if there is any good advise. Venlig hilsen / Best regards Astralis A/S Karsten Aarhus Pc-koordinator Tlf. +45 7678 5500 Direkte +45 7678 5580 Fax +45 7878 5502 Mobil +45 2725 1680 www.astralis.dk
