I recently had to reinstall Active Directory on a Windows 2000 server. All sorts of problems started because I think the disk became full (Microsoft Knowledge Base Article 259278). I now need to get Exchange server working with it again. I have reinstalled Exchange because it had become corrupted as well. Everything seasmed to be OK appart from I can not get the system Attendent to start which means I can not start the information store. I have looked in the Microsoft Knowledge base but it says it may be because Netlogon is not running, but it is. The server is the Domain Controller. Does anyone have any ideas? Thanks.
