My SharePoint farm was running properly. Suddenly all web applications were inaccessible. When checked Widows event log I found the following error.
Target Principal name is incorrect,Cannot generate SSPI Context
We are using NTML authentication. I tried to connect to SQL Server using SQL Server Management Consle. It is giving the same error. I can log into the SQL server locally but not from any other computer in the network. Only SQL authentication works within network, windows authentication is not working. Windows authentication is just working locally
What can be the issue?
