No Such Host Is Known - Please Help

[rodd]

Hi all,

I'm new to everything website related, could someone please help me??

 

I have a website made in ASP.Net using Visual Studio 2010 with 3.5 framework.

The site seems to be working fine, except for pages that contain a datagrid linked to my database, database1.mdf in the /app_data folder.

 

I get this:

No such host is known

 

Description: HTTP 500. Error processing request.

 

Stack Trace:

 

 

 

System.Net.Sockets.SocketException: No such host is known

Like I said, I'm completely new to this and don't know what this error means or what I can do, so any help would be greatly appreciated.

 

Thanks in advance

Username? Server? I'm not experienced with asp, but I do know you need to be registered on Johnny to use it here.

Hi,

Thanks for your reply.

Username is roddd and server is Johnny. Like I said the site is working in general, it's just the pages with datagrids linked to the databases. The other ASP pages are ok.

Thanks for your help
