The error is as follows:
The server S3.Posto.local does not have the service principal name (SPN) MSServerClusterMgmtAPI/S3. THis is needed for cluster APIsto authenticate to the server by using kerberos. To add SPNs on the server computer obnect use the Set-ADComputer cmdletwith the -SetPrincipalNames parameter.
Both systems are in same domain and are windows 2012 R2 standard.
S1.Posto.local is always reconigzed but never S2 or S3. Tried doing cluster with both.
Anything will help.
