clustering error no 7.1.1 TN Console

Hi there everyone,

We have IS 7.1.1, with a database components that were upgraded from 6.1 to 7.1.1.
OS is solaris 9 64 Bit.

Everytime i try to query the profiles i get this.

Failed to create/get distributed cache ‘’; reason: java.lang.IllegalArgumentException: Invalid multicast address:; – check configuration

We tried to cluster our IS but our multicast is turned off. I dont know why am i getting this error.

Any help would be monumentally appreciated.
