One of my clients is running single instance of Exchange 2000 on a W2K server. This morning, the Exchange server crashed due to a HD becomming full. Prior to the crash, it was functioning perfectly. The hard drive became full because one workstation was submitting about 50 requests per second for Windows Updates (SUS had previously been installed on this server), and the IIS log files used up all of the available drive space. We were able to resolve the SUS problem, and clean up the hard disk. After a server reboot, it appeared as though everything was functioning perfectly.
They are able to send and receive internal mail without difficulty, and are able to *receive* SMTP mail without difficulty. However, all *outbound* SMTP messages are being delayed about 30 minutes before delivery. No settings on the Exchange server have been changed, and DNS appears to be functioning properly.
Any help would be appreciated.
