Pre-login handshake woes with connecting directly to SQL Azure

Question

We are currently experiencing a rather troublesome problem in our development environment with the following message...

A connection was successfully establi         


        

Answer 1

What does your connection string look like? Not sure if you've tried this yet but I remember having a problem similar when using a remote SQL connection to SQL Azure and found that I had to set:

Trusted_Connection=False;Encrypt=True

and remove any Connect Timeout from the string entirely.

Answer 2

You need to scan for Non-IFS Winsock BSPs or LSPs which not compatible with the FILE_SKIP_COMPLETION_PORT_ON_SUCCESS flag ,problem results primarily from non-IFS LSPs Being installed.

Just run "netsh WinSock Show Catalog" from command prompt , and check any "service flag" which doesn't look in the format of 0x20xxx

In my case I found that "Speed Accelerator" with service flag 0x66,removing this software solve my Problem .
