To run SBS apps in separate servers you need an upgrade kit from Microsoft. You also need to buy an upgradekit for the cal. After that you will be able to separate the apps. As I said before you must also upgrade the cal for Exchangeserver and for Win 2000. You lose the cal you have for the SBS, if you have 45 cal you get 5 Exchange, 5 Win 2000, 1 ISA Standard 1 processor. You will be able to keep the fax/modem apps (If you accept to have them on the server you are running the updatekit on. Best Regards Magnus Hellström IS-Manager Neoventa Medical AB
