David,

Yeah, I tried that too and it worked about as well as BP's recent
efforts. Thank you for the response regardless. Oh well, maybe I'll
release a patch for rdesktop and help people lock out accounts more
often.

Use the -b switch with tsgrinder to get past the banner.

tsgrinder.exe -w wordlist.txt -u administrator -b 192.168.1.1

Thanks for writing back; however, the question still stands with
regard to the legal banner ;)

I never do bruteforce on this except checking weak passwords a few times
mainly because of account lockout, which is not a desired option in pentest
engagement.

Hello:

Trying not to reinvent the wheel here, does anyone have any idea with
regard to a method for performing dictionary attack against terminal
servers that have the legal banner enabled? I'm finding that in all
cases the legal banner seems to stop the password guessing. I'm
guessing that a modification to simply send a keypress through is all
that is needed.

I've tried this with rdesktop brute force patch (both patches),
tsgrinder, tscrack, etc. but to no avail. Any plans by the authors of
those tools to update or release source :P
