Hi guys, I run exchange 2000 with service pack three and this server is a domain controller. For some funny reasons I notice that the services just freeze and exchange stops working. All the services are still running, but when I send a mail to anybody including myself, the mail leaves the outbox but is not delivered to its recipient whether locally or externally. If I try to restart the IS service it just hangs. The problem only gets resolved when I reboot the machine. After the machine reboots and is working well, it works for another 4 days and freezes again. Can anyone please help me with this?
