mount error(112): Host is down

Got the following error when trying to mount a CIFS file on RHEL 6.5:
[root@tama etc]# mount -t cifs --verbose -o username=goldengate_DBA //lacsqltzgprd4/GoldenGate /mnt/GoldenGate
Password:
mount.cifs kernel mount options: ip=10.50.243.13,unc=\lacsqltzgprd4\GoldenGate,,ver=1,user=goldengate_DBA,pass=********
mount error(112): Host is down
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

It has been working fine until now. Not sure if it's a coincidence, but the problem started after we did the Kerberos password change over the weekend.
Thanks.
