SQL - A connection was successfully established with the server, but then an error occurred during the pre-login handsha

I am getting following error when i am trying to connect Production DB from Local Environment.

I was able to connect Production DB before, but suddenly i am getting following error, any idea?

A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The handle is invalid.)

 

 

Solution

1) Clean your VS.Net Solution

2) Rebuild Project.

3) Reset IIS

4) Run the project again.

Basically that solved my problem, but in my case i was not getting this error and suddenly my local environment starts giving me above error, so may be that trick work for me.
