Do suggest how this can be res

Hiya,

either it relates directly to the error message, stating that the room.com domain cannot be contacted. If indeed room.com can be contacted, you (or the service trying) might lack the permissions to create SPN's in the domain.

Creating SPN's requires special permissions on the domain. Usually done with Domain Admin privileges or with a priviliged account with the "Read servicePrincipalName" and "Write servicePrincipalName" access control settings in the Active Directory.
