I finally managed to make it work again… I turned off “auto login” and I reentered user name and password (anonymous and blank respectively). This was one of the first things that I had tried, but even though I had erased previously stored login data, and had turned off auto login I couldn’t get the “enter user name and password” window to pop up!! I don’t know why or when this solution started working…
The reason that it took me so long to figure out the proper solution is that WD did not prompt me to reenter username and password when it failed to connect… In fact, at the beginning, there wasn’t any feedback whatsoever when trying to access my network share.
Unacceptable behavior
