One part of the "fixes" for networking and printing from Win7 to OSX involves making sure that that the LAN Manager Authentication Level is changed to "Send LM & NTLM - use NTLMv2 session if negotiated". http://forums.macrum...read.php?t=776672
Of course, Home versions of Winders, like on my new Toshiba R835-P88, don't have that.
So I can't print to our Lexmark printer on the Mini from my Toshiba laptop running Win7 without sending MS $65 to upgrade to Win7 Pro. Naturally XP Home on a Lenovo netbook didn't have these issues.
Grr...
Cheers,
Scott.
(Who thinks he will be spending more time with Linux on the Toshiba...)
