Hi everybody, This is my first time in the list, so I hope you could give me more ideas. Have the following environment: A Win2k DC which also is Exchange2K server, this is the lonely server in the organization, I call it THE server. This DC has problems with some FSMO roles with impact on the end users: things like we can not add more machines to the domain. However, the AD tools run ok, even I can add users or groups to the domain, only if I run it locally on the server, of course. I have received the server with this problems from a previous administration. The thing is: I want to reinstall the server. BUT I have this problems: - I need to preserve the AD accounts in order to associate them with their mailboxes once I have restored the exchange services. - I think that a System State backup of the server will preserve the accounts, BUT maybe also preserve the misconfigurations I described. Has anybody experienced with a similar situation?? Any suggestions will be well received. 10xs!!! Daniel
