While trying to install GroupWise Messenger on a new GroupWise 6.5
install, I am receiving this error when trying to extend schema.

NDS error -604, encountered during program execution. Error description: .
Failed to add schema class: nnmSystem.

I have completed the Health check
NDS Health Check Procedures - Cross Platform - TID10060600

Looked at
Error: "NDS Failed to modify schema class: user. NDS error: -659" -

and finally completed Declaring a new epoch.
Declaring a schema epoch - TID10066252

Any thoughts?
