net.exe problem - System error 53 has occured

I am trying to do some quick information gathering and went to map a new drive. After using a good old:

net use q: \\192.168.0.123\g$

I got this:

System error 53 has occurred.

The network path was not found.

I was able to ping the machine, so, I knew something else was going on. A quick Google reminded me a of a nice site I like to frequent:
