CIFS VFS: SERVER NOT RESPONDING...

You might see this message when you shutdown or restart, and the system seems to hang for a few minutes. Here's a fix:

Navigate to /etc/rc0.d
cd /etc/rc0.d

Now you want to look for a file named ***umountnfs.sh -Where the stars might be different depending on your system (mine was S31umountnfs.sh). Now just replace the first part of the filename with K15.
sudo mv S31umountnfs.sh K15umountnfs.sh

Repeat the process for /etc/rc6.d and the error should be fixed!
cd /etc/rc6.d
sudo mv S31umountnfs.sh K15umountnfs.sh
