mapping network drive, sh.exe": no such file or directory

mapping network drive, sh.exe": no such file or directory

I'm trying to learn to use the command line and I googled on how to map
network drives from the command line. I came across using the net command
and the pushd command. We have a mapped network drive at work that I can
go to in Windows Explorer by doing
\\sf-testers\test-datasets\
When I try
pushd \\sf-testers\test-datasets\
I get the response:
sh.exe": pushd: \sf-testers\test-datasets: No such file or directory
When I try
net use x: \\sf-testers\test-datasets
I get:
System error 67 has occurred.
The network name cannot be found.
I'm running Windows 7 on bootcamp. What am I doing incorrectly? Thanks in
advance!
