Windows 10 April 2018 update Problem

Hello,

Since Windows 10 April 2018 Update came out, all the clients that have been updated cannot connect to the local server where the application and database are located, while those that have older version of Windows 10 or Windows 8 and 7 can.

I have tried installing HFSQL Control Center on the client machine and tried to connect to the database on the server to see if it would work, and it connected without any problems.

Problem happens when I run my application on the client machine, I get an error saying that connection could not be established.
Error code: 74000
Level: non-fatal error
WD55 error code: 4000

One workaround was that I copied application .exe file and all .dll files to the local machine, and when I run it like that, it also connects to the server without any problems.
This is bad solution as I want to control all clients from the server, but it is a temporary solution until I find out what they did in Windows 10 April 2018 update that is causing these problems.

Did anyone else have any problems with Windows 10 Update??

Kind Regards,
Rasta
