Starting with firmware version 5.1, shares accept only NTLMv2 authentication by default.  Some older PCs may only support NTLMv1.  To enable NTLMv1 authentication for a CacheDrive, do the following:

  1. Go to the Morro Cloud Manager.
  2. Go to Devices, then select your CacheDrive.
  3. Go to Advanced and change the NTLM Authentication setting by selecting "NTLMv1 is permitted".
