Solution 1: Do settings again. Put the username and password one more time to reach network drive.
Solution 2: Increase shadow storage limit on all drives
The shadow storage size can be checked and manually changed through a command prompt. Open command prompt as administrator rights.
- To check the current limit set: vssadmin list shadowstorage
- To change the limit: vssadmin Resize ShadowStorage /For=X: /On=X: /Maxsize=XX%
- This will resize the limit to XX percentage size for the X: drive.
- We recommend setting the drive to 30%.
