3 Node Cluster
NetWare 6.5 SP5
iManager 2.6

Unable to connect to the Cluster to manage it via iManager or ConsoleOne

In iManager I select the cluster object and IE sits there for about 5
minutes before returning a Service Unavailable Error 503

In ConsoleOne everything is greyout with Not Connected in the Top right
corner of the screen

Everything was working fine up until a few weeks ago...(well with imanager

Any suggestions gratefully accepted!! Cheers, Adam.
