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.)

I was trying to run asp.net website in local PC, which has connection string of Production DB, following is stack trace for error I am getting in local environment.

Any idea what might have gone wrong here?

Answer 1

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.
