Has anyone messed with winexe? It's a very cool program. Let's you get into Windows from Linux.

[]# ./winexe -U domain/username%*****//my.site.com 'cmd'
Microsoft Windows XP [Version 5.1.2600]

C:\WINDOWS\system32>
However it seems to have some limits. For example, I can't get it to work with "wmic" commands. For example:
[]# ./winexe -U domain/username%***** //mysite.com 'wmic share get caption,name,path'
it hangs...
