Could not locate nlb on the specified computer windows 2008

I have tried approaching this from the new server - I can load the cluster, and I can add this server to the cluster, but once I do, NLB Manager becomes unable to load the config from the other hosts.

Specifically the last time I tried it I got host is misconfigured error for one of the other hosts This is a host has been in the cluster without issue for years. If I remove the new host from the cluster, and refresh the cluster, it loads the other hosts without issue.

Edit : I have now tried manually 'joining' the cluster by manually entering the cluster's IP addresses as extra IPs in the new server, then click the checkbox for 'Network Load Balancing' in the network properties screen.

This seems to work, but if I open NLB Manager on one of the other servers it shows this host as unreachable, and I cannot ping it. As soon as I reverse those manual changes I can then ping the server fine from one of the other servers.

It seems that attempting to join a cluster renders the server un-detectable by the other servers. To answer my own question: It might not be possible to do this. I looked in the event log on the new server after some recent attempts and saw this An unsupported legacy host 3 was discovered on the network. The OS version on this host is no longer supported in a mixed cluster configuration. The cluster will remain in the converging state until all deprecated legacy hosts are removed. Sign in.
