I'm facing issue with SQL Server connection is hanged for all clients which are using AD user while SQL and NAV services are running normally.
Unless I restarted DB server, It will work fine.
Somebody help me please!
That can have a lot of causes.
Maybe you have a network / DNS issue ?
Hi Daravuth ,
Please try to restart your SQL service and NAV Service using local account and then choose Admin credentails, restart the services and then please try again.
Also please try to check Event Log.
Hi, As Inge and Nitin said, there are many causes for this, and if restarting the server doesn't fix it, it is recommended to check the logs in the Event when the problem occurs.
Hope this will help.
This is event log in SQL Server before restarting DB Server:
The SQL Server Network Interface library could not deregister the Service Principal Name (SPN) [ MSSQLSvc/DB-SRV01.vattanacgroup.com:1433 ] for the SQL Server service. Error: 0xffffffff, state: 63. Administrator should deregister this SPN manually to avoid client authentication errors.
What is the root cause?
Hi, This seems to be a SQL problem, I found some information, I hope some of them can help you.
