A network-related or instance-specific error occurred while establishing a connection

Hello,

I got this error this morning :

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - No such host is known.)

And more, some images (or pictures) are displaying "X" rather the image.

Anyone can help?

 

Give us a link to the page where the pictures are showing the X (just means it wasn't found or couldn't load).

Also, for your network-related issue, post the connection string you have. If it was working before, you should try recycling your application pool in the CP, just go to the IIS Tools > Recycle App Pool tab. Sometimes this work, but if it doesn't give us the connection string you're using. MAKE SURE YOU DON'T POST THE PASSWORD or any sensitive information though. I see this a couple times in the forums

 

Working fine until this morning

Thank for your reply.

But pictures are in area reserved to my clients. Some of theme shows a "X" and some display correctly.

My string connection working well before and I do no change in my database.

It's seem a server problem. BTW, I open a new IE8 window and everything is back to normal. Weird... I will keep a eye on that because a have to provide a 99.9 uptime service!
