Can't connect to SAP B1 integration service

Dear All,

I just installed a new server. Dashboard works fine on DB server.

When I login SAP from the terminal server, everything is fine except Dashboard.

The error message is

Can't connect to SAP B1 integration service

In the Microsoft service window, ensure that this service has been started

Is there anything I should check on the DB server ( SAP B1 integration service installed) or anything on the terminal server?

The windows firewall is inactive. They may have other firewall. If I have to ask the IT person change anything on the server, what should be change?

Thanks in advance!

Regards,

YJ
