NAB and Windows Users

Hi,

I am trying to find out how to sync a Windows Group with a Group in the NAB. The rule is if the user is in the Windows group then they should be in a corresponding Group in the NAB. I am having trouble figuring out how to access the Win Groups. I have managed to do it using the showmbrs.exe that comes with the Windows Resource Kit but this

way is really clumsy and I thought there must be a better way (i.e. not using a command line tool). I would prefer to be able to do it on any WinNT, Win2K, Win2003 server, whether they have Active Directory or not, but any hints for either circumstance would be greatly appreciated. I hope I have provided enough information.

Thanks,

Greg
