We have a sql cluster. Originaly it was all working. At some point the TCPIP stack on sql1 got corrupted. After repairing the stack the cluster service will not start on that server. This is a production system so we are concerned about evicting that server from the cluster and possibly losing the other server that is still working and using the clustered drives. One note: while troubleshooting the TCPIP stack issue we removed the server from the domain. It is now back in the domain. Is it possible that removing it from the domain and putting it back in that we need to evict and add it back in to the cluster because the QUID changed?
