can you confirm if client can telnet to master over port 1556 ?

if Windows Firewall is running on Client then make incoming rules to accept connections over 1556, 13782 and 13724. If its a DB (mssql or oracle) server then also add 13720 to the list.

Ofcourse I registered with the client os firewall.
I don't think it's because of the port.

I would certainly search Microsoft site for suggestions and solution.

Error 1935 is a Microsoft error.

@yeonggeun please be careful to use a statement like 'of course'.
This implies that we know you and know exacly what you did.
If you don't document each step that you have followed, then you need to be prepared for 'basic' questions.


Do you have any anti-virus software running on the server you are trying to install the client on?
