Hello,

When using Ethereal 0.9.2 on a WinNT platform, I get the error message that
the H225 messages "admission request/confirm" and "registration
request/confirm" cannot be decoded. (error message "failure to decode"
appears in the capture window next to the packet) In the GUI I can see that
they are H225 messages, and I know from experience that they are
registration/admission request/confirm messages.  WIth H225 setup and
alerting messages, there is absolutely no problem, these are decoded just
fine.

I have installed the correct WinPcap version as stated in the documentation.
On one NT machine all works well, and the H225 messages are correctly
decoded, on another machine, it shows that they are H225 messages, but does
not decode them, and on yet another NT machine, they aren't even recognized
as H225 messages. 

I have the H323 plugin Version 0.0.3 and packets are captured in promiscuous
mode. 
Can you tell me what might be the problem ? Perhaps some kind of setting in
Ethereal that I am not familiar with ?
Thank you in advance.
Vaya Willemen.
