Here is a tcp dump and alert file.
Obfuscated and on a false account, in case the alert is right...
Thanks

The "... MS Terminal Server no encryption session initiation attmept"

False Positives:
Connect to a MS Server using rdesktop.
The rdesktop man page seems to indicate that default use is encrypted.
From the rdesktop man page...
-e Disable encryption. This option is only needed (and will
only work) if you
have a French version of NT TSE.
-E Disable encryption from client to server. This sends an
encrypted login
packet, but everything after this is unencrypted
(including interactive
logins).
Either the rule is misfiring or rdesktop is not behaving as advertised.
Evidence suggests a misfire.
