Hi all, Recently there was below error listed in Exchange 2000 and Whole storgage group went down. I have checked there's enough disk space in server. I tried to mount store manually, but didn't work. After restarting server storage group came online. As such there wasn't any changes we have done prior to this event occured. Could you please share, what's root cause or permanent fix.

The "not enough storage to process command" doesn't actually mean a problem disk space. It is one of Microsoft's generic errors that can mean any number of things. If it only happened once, then I wouldn't worry about it. It may well be a memory issue which was cleared by rebooting the server, but it is impossible to know. The event log doesn't really say enough to know the cause. Simon.Simon Butler, Exchange MVP. http://blog.sembee.co.uk , http://exbpa.com/

Yes, Its looking memory leak issue in server, you can get better idea if server have generated memory.DMP which you can analyze. Anil
