Connect to a terminalserver farm with session broker

Hello...

I've got a problem accessing the Solaris OS using rdesktop on a terminalserver farm with TS Session Broker and W2K8R2 with NLB.

I get the following error message:

user@xxx [15:42] /h/user/Desktop 150 > rdesktop terminalserver

WARNING: Remote desktop does not support colour depth 24; falling back to 16
WARNING: rdp_in_unistr: iconv fail, errno 88
WARNING: server sent an unexpectedly long string, truncating
Segmentation fault (core dumped)

Does anyone know this problem?

I have the problem with opensolaris, opensuse ...

Many thanks for your help.

Regards Christian
