I get the following error at random intervals when executing my SQL Queries
Message: System.Data.SqlClient.SqlException (0x80131904): A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)

I thought this might be due to a dropping network connection, is this correct? How do I code around this?

Yes, "transport-level error" is a "geek talk" word for "network". This could also happen when the network connection becomes stale, for example, because your server gets rebooted after you obtain a connection and hold on to it for too long.

Unfortunately, there is not much you can do about network connections. You can use try
/catch
, look for SQL exception, and retry with a retry count, but eventually you report this to your end users.
