Hmmm... no, I don't think its a problem. I haven't added that to my program
that I've been working on (a netbios password brute forcer... if I didn't already mention),
but I think it should be simple to add. The for loop should create no problem.
If you are getting an error, I would have to take a better look at your code.
I just quickly responded to this last nite cause I knew the file would be helpful and I was in a hurry.

Another thing to consider would be to thread your program to scan all of the machines independently.

Hope this helps.
