Connection To Nas Drive Keeps Failing

Start computer the NAS Dive Has two Drives they show up try to do a backup it fails terminated by critical error Click on the Network location for the NAS Drives it states error occured while reconnecting etc etc Connection not restored Says this for both Drives in the Nas N & P
This happens everytime windows updates and has resolved itself on occasions but I cannot get this to work now. Is there a fool proof way of doing this so it does not keep failing. I could shut the computer down restart and it would work but not now the NAS is live and waiting Computer not connecting to the NAS

Are the shares 'public' or do you have to use a username and password?
Are you mapping the drives in Windows with net use?
If you have the drive mapping in a batch file at startup or login, try running it as an Admin.
Synology giving you the shares are in use by the user or some such error?
Log into the Synology and kick - disconnect the connected SMB users - top right of window, click the widget icon and you'll see connected users. If you kick the Http, you'll get disconnected.
After you kick them, try connecting to the shares again.
