SQL 2012 hosted database, losing connection on client

Hi,

I have a remote server which includes MS SQL 2012 on it.

I am hosting a database for a client, that he connects to with a remote Access app.

Recently he has reported multiple disconnections from the database per day, which occur from all sites using the database, so it sounds like the server end rather than the client end.

Looking in the SQL Server Logs in management studio, I see a lot of entries like:

SSPI handshake failed with error code 0x8009030c, state 14 while establishing a connection with integrated security; the connection has been closed. Reason: AcceptSecurityContext failed. The Windows error code indicates the cause of failure. The logon attempt failed   [CLIENT: ***.***.***.***]

(There is an actual IP address in the message, which I have removed!)

Any ideas how I can fix this?

Richard

Isn't a SQL Server problem. Seems to me that you need to talk with the people that manage the DNS.

That's interesting. What is the issue with DNS? I manage my own DNS through a company called 123-Reg

Since you removed an IP address I think you should check if that IP still registed in DNS. Maybe is pointing to some other machine.
You can also check for the host file. Some old entry that you need to delete?

I think you might have misunderstood my comment. When I referred to removing an IP address I meant that I removed the actual address from the text that I posted, not that I have changed any IP settings on the server,

Greetings rpm.  Lets look in the direction of authentication of the logins into the databases.  I assume some connections have in the past, and still do authenticate correctly and are working normally.  Are the connections mixed between using SQL authentication and Windows authentication?  (And if Windows... are they domain credentials?)  And if domain... are you using NTLM or Kerberos authentication?

I'm going to guess that you're missing Service Principle Name entries.

But there are a few other possibilities, and here's a good blog entry for troubleshooting.
