did some one turn off multicasting in your CLAN ?
or did someone change the CCMA send IP adress ?
the other services i would check would be
CCMS_SDP service
IceRTD Service
and also D:\nortel\ICCM\bin
try the MRCV.ini and MRCV.exe tests
and the Multicast tracetool tests
if you didnt know how to run this, i'll make a detailed post later
im too lazy now
