TCP connection on windows 10

Hello everyone,

We are using a labview (2015) programm to access a database. It has been working just fine for the pasts months, but I can't have it to work on the new windows 10 (april update) computers. I've reduced the test to a simple TCP open connection which give me error code 1 TCP: Verbindung herstellen. 
From this same computer I can access the database from other softs than labview...

Have you heard about something like this ??

Thank you very much 
Martin
