Hello Dochelp team,


"COMM_VVECTOR is the local member version vector. If the local member 
knows m originators in its
version vector, there MUST be m COMM_VVECTOR elements in the packet, one 
for each originator.
COMM_JOIN_TIME MUST be the current time."

Traces between Window servers show no COMM_VVECTOR packet and no 
COMM_JOIN_TIME (for a SYSVOL replication), you can see it in the trace 
http://imaps.matws.net/mat/misc/joinfrs.gz  at packet 4643. To decode it 
you'll also need the attached keytab. It's worth noting that example on 
page 138 didn't show this packets as well.

Note in order to see the FRS packet you'll need a pretty recent version 
of wireshark as I did the dissector for it not so long ago, you can get 
a nightly build of wireshark at 
http://www.wireshark.org/download/automated/win32/ and you need a 
version with a SVN revision > 38476.

Can you explain ?
