Also, the issue may be caused by “User Profile Service”. Please ask FPT to verify this issue.

     In addition, I noticed the following Event ID errors. Microsoft Resource Management Service Event ID 0 error “Service cannot be started. System.Data.SqlClient.SqlException: Cannot generate SSPI context.”

     A SharePoint Foundation Event ID error 5586 “Unknown SQL Exception 0 occurred. The target principal name is incorrect. Cannot generate SSPI context.”

    Forefront Identity Management Event ID 3 error “.Net SqlClient Data Provider. System.Data.SqlClient.SqlException: Cannot generate SSPI context.”

Please tell me that what is the issue here?
