Constantly need to remap network drive ReadyNAS

Something Microsoft did in the latest Win10 update has made this worse for me.  I use the same user name for my computers and NAS, but different passwords, which may be exasperating the problem.  Windows is obviously sending the PC user name and password to the NAS when I re-boot the PC, and that password is wrong.  But when I try to access the NAS, it no longer asks me for the correct user name and password, it just says the device name is already in use but I don't have access.  That used to happen once in a while, especially after installing a Windows update, but now hapopens every time after a re-boot.

Is this similar to what you are seeing?

I intentionally have the passwords different and don't want to store the NAS password in the Windows Credential manager, so it appears I'm stuck with that because programmers at Microsoft are ignorant of how users actually use their product.  When it was happening once in a while, I made a batch file that re-maps everything and put it on my desktop.  Now, I have to use it every time I re-boot.  This is my file:

net use * /delete
net use B: \\192.168.0.42\BJH /persistent:yes
net use M: \\192.168.0.42\Music /persistent:yes
net use N: \\192.168.0.42\Videos /persistent:yes
net use O: \\192.168.0.42\Other /persistent:yes
net use T: \\192.168.0.42\Temp1 /persistent:yes

It will ask me for the user name and password for the first mapping, and then use them for all the rest.

Of course, the /persistent:yes part really isn't accomplishing anything any longer, so I could remove that.  If I did that, I wouldn't have to confirm that I want to delete the connections that aren't really connected at all because they would not be there at re-boot.

FYI, BJH (my initials) substitutes for my home folder because I dislike the limitation of the built-in ones, and the rest is pretty obvious.
