SSR -Network Name no longer Available

First off i want to say that i have Backup Exec that runs everynight on the same server and this never happens, but when i run my System Recover Backups I get the same error everytime:

-Error ED800019: The recovery point file '\\192.168.111.5\symantec system recovery\LantekServer\LantekServer_C_Drive.v2i' could not be opened.

--Error E7D1000E: Unable to open '//192.168.111.5/symantec system recovery/LantekServer/LantekServer_C_Drive.v2i'. It does not exist.
