ISSUE
When you are trying to mount a windows share that uses NTLM SSP with packet signing.
RESOLUTION
There are two different commands that you will have to run to add the NTLM SSP in the cmc_nas script. It just depends on the protocall that is required.
You will need to ssh in to your appliance then you will run either one of these commands then you will be able to add it as a protected asset to backup the share.
sed -i 's/ CIFS_MNTOPT=",/CIFS_MNTOPT=",sec=ntlmssp,/' /usr/bp/bin/cmc_nas
and
sed -i 's/ CIFS_MNTOPT=",/CIFS_MNTOPT=",sec=ntlmsspi,/' /usr/bp/bin/cmc_nas
