I run up 'netsh' on my Windows XP box, and type
help
One of the options is wins (to change to the 'netsh wins' context).
From the netsh context I can type "wins" and I get into the wins context just fine.
Problem is, from another machine on the same domain, I can list netsh options, but wins is missing.
Why would this be?
No idea, why this Windows XP is missing the WINS tool. Windows Vista's netsh doesn't include it, but it should be available on Windows XP.
As a workaround you could use Microsoft's
NBLookup.exe command-line tool
Turns out the Windows 2003 Administration Tools Pack installs the WINS component into netsh.

What service pack of XP are you running?
I just fired up an XP SP1 vm, had a look at the command list and the winsock ("wins") is missing. So that machine looks like it needs to be upgraded to SP2 at least.
