Our email server stopped responding, and upon reboot, would not connect to the domain. The onsite guy used the reset account command in the active directory gui, rebooted, but still would not connect.
If I understand it correctly, now that he has reset the machine account, the only way to get back on the domain would be to unjoin\rejoin. I tried netdom without success (I assume because he reset the account). DNS and connectivity seem fine because I can ping back and forth via address and name. When logged in local (it uses same administrator password as the domain) I can access the system shares of the PDC via unc.
Is there a procedure to backup the CA database, unjoin\rejoin, and restore the ca information without breaking Exchange?
It's a single Exchange 2003 Enterprise on a 2003 member server. The PDC is also 2003 server.
