How do I Monitor a UNC path?

From server1, I have access to the desired UNC path, and this same user is running splunk, so I know access is not an issue.

\etc\apps\search\local\inputs.conf

[monitor://\\SANCIFS_TDC_NETAPP01A.SAN.MyCompany.Com\CIFS_COGNOS$\Test\Logs]
disabled = false
host = sancifs_test
index = default
sourcetype = motio_test

I have tried many different permutations of the forward and back slash for my monitor stanza, but nothing has worked so far.

What am I doing wrong?

Thanks, Sean
