I'm in the middle of uppgrading 5.5 to 2000. I have 5.5 installed on w2k server. I installed ADC on both the exchange 5.5 server and the one I plan on installin Ex2k on. During trouble shooting I guess I somehow deleted the the user account exchange 5.5 uses. However the services are still running and currently working.*knock on wood* I tried restarting one of the services and it says bad username or login information. I looked in AD and the account is gone. I tried creating another one with the same name and password, It will not let me. NAV uses that account also. So i have a big problem. If I reboot the machine. NAV and exchagne will not work. My question is how can I create/assign another account for the exchange 5.5 server and NAV.
