I'm looking at the logs and it appears SSR is encountering periodic network issues. The error being returned to SSR by Windows 2003 when the connection is made (or attempted to be made) is:
"Unable to establish a network connection to \\bckup2-2k8-main.xxxxxxx.com\d$. Error 000004b3 - No network provider accepted the given network path.” (domain name replaced with x's)
According to Microsoft, under Windows 2003, one or more of the following condition could be true:
- There are network connectivity problems.
- There are name resolution issues with, for example, Windows Internet Name Service (WINS) or Domain Name System (DNS).
- The Remote Registry service is disabled on the client computer.
- The Microsoft Windows Server 2003 firewall is blocking communications between the SMS Advanced Client and the SMS site server.
- The Server service on the client is not started.
- File and Printer Sharing for Microsoft Networks is not installed on the client computer. (Note If File and Printer Sharing for Microsoft Networks is not installed on the client, you receive the following error message (in the event log): Error 67 - The network name cannot be found.
(SSR uses the Windows API for all network connections. There are no proprietary connections made directly from SSR to the backup destination.)
