Connection Error on starting GUI after installing SAP ABAP Trial Version

[Former Member]

I bought the new edition of ABAP Object recently.

I tried to install the SAP NetWeaver 2004s ABAP Trial Version that came with the book. After installing the WAS and SAP GUI 7.0.

Then, I set up the server properties as stated in the CD.

System Connection Parameters:

Description: NSP local

Application Server: localhost

System Number: 00

System ID: NSP

When I try to connect to the server, it gave me the following errors:

partner '127.0.0.1:sapdp00' not reached.

......

Error Text: WSAECONNREFUSED:Connection refused.

Please advise.

Thanks.

also make sure that localhost is pointing to loop back adapter ip address. (10.10.0.10) in the hosts file

Hi, Prince.

Durairaj,

I actually did not install MS Loopback Adapter in my laptop (after my last uninstall).

Should I reinstall it again to make it works?

Thanks.

Durairaj,

I have installed MS Loopback Adapter, and also point my localhost to the IP:

10.10.0.10 localhost

But I still not able to connect to NSP local system.

The network connection for the Loopback Adapter is showing No or Limited Connection, is that because of this reason?

Thanks.

Hi Kent,

Make sure that your firewall is off, It seems that your firewall is currently blocking this network connection.

I have disable the firewall, and try to repair the Loopback Adapter. During the process of renewing IP address, it failed.

What else I need to do to make the loopback adapter to work?

Thanks.

Just manually enter a static ip like 10.10.10.10

and subnet mask 255.255.255.0
