Connection to remote host in NWDS preferences (SAP Instance not reachable)

Hi Experts

I am trying to connect to a SAP Web AS running CE 7.1 with Netweaver Developer Studio as described [here|].

The u201Cinstance hostu201D is a remote host. When I try to connect with NWDS 7.1 SPS 5, I get the error message:

SAP Instance is currently not reachable. Check if the SAP Instance number is correct.

However, with NWDS 2004s SPS 13 (installed on the same machine) and message server port 3901, I can see the host in the J2EE view with two green dots (icm, server 0) and one grey dot (debugproxy). NWDS seems to connect (in spite of the grey dot).

Do I have to configure anything else in NWDS (message server port)? Does the debugproxy have to be started?

Thanks for helping!

Kind regards

Hi Bettina,

have you already checked, if there is a Firewall between the NWDS and the Application Server?

In this case, check the Port 5xx13. Replace xx with your Instance Number. In NetWeaver CE the new MMC Applet is lisitening.

I hope this hint will help you.
