Hi,
  I am trying to write a dissector for MS-DCE RPC for messages sent between Outlook Client and the Exchange Server.
    I have started to capture the  messages using Wireshark(1.2.0), but getting message with some 180 bytes of stub data without decoding.
 
  So, I have started to write a dissector for decoding EcdoRpcExt2 message. But since the message is compressed , I am getting a compressed message in the following format for the Hex-dump message.
a4 a5 a5 a4 a5 a5 4e a4 a5 a5 a4 a5 a5 a5 a5 a5 a6 a5 a5 a4 a4 ad a5 a4 a4 a4 a5 a7 a5 a4 a9  a5 a5 a5 a5 a5 a7 a5 a5 a5 a4 a9 a5 a5 a5 a5 a5 a7 a5 a5 a5 a5 a5 a5 .
 
    Please provide me info as I how I need to decompress and decode the message .
 
Regards,
Arjun
