Mini SAP connection error

[Former Member]

Hello SDN Community,

When I log on SAP then following error occures.

"Partner '127.0.0.1:sapdp00 not reached

WSAECONNREFUSED: Connection refused"

I installed mini SAP on my own laptop and it does not have any server connection. Is it poosible that is the problem?

Problem is solved by

1) uninstalling the software .

2) renaming the computer name (name should be small in length)

3) reinstalling the whole thing again.

It worked in my case.

Hope this helps !!

Bilal,

I have tried what you said but no luck.

I think my problem may be due to the fact that my machine has Windows XP Home edition with only 512K of Memory.

I can go into Maxdb and SQL Studio. I can also ping both my localhost and my Microsoft Loopback Adapter.

When I go to Services.msc I can see that SAPNSP_00 is up and running as is SAP DB WWW. However I still get the same error message when trying to log on.

Does anyone out there know if you have to have Windows XP Professional version?

Also is 1GB Memory a must or does minisap just run slowly with 512K?

Many Thanks.

I dont know about win home, but from the requirements its stated:

Operating System:

Windows XP Professional (Service Pack 2) or Windows Server 2003

if thats not da prob, the fact that you still got the same error means that sap still trying to connect to 127.0.0.1.

From other thread some solved by uninstall&installing sap gui again, but ive solved mine by the help of this thread:

Basically i just changed my loopback ip address with 10.10.10.10 and go to

C:\WINDOWS\system32\drivers\etc open hosts file

and change

127.0.0.1 to 10.10.10.10

so its the same as the loopback ip.

dont forget to start the application server before login in.

Did you install MiniSAP 46D or the NetWeaver Sneak Preview ABAP Stack?

For the first...You need to open the DOS window and keep it running...

For the latter...Do you have the Microsoft Loopback adapter?

Did you start the Management Console?

I too am getting this error

partner '127.0.0.1:sapdp00' not reached

and WSAECONNREFUSED Connection Refused

I downloaded the SAP Netweaver 7.0 Trial version and unpacked the first file etc. and then installed the software. During this process I got an error = 200 message Java error.

I then installed Java Developer Kit thinking that that may solve the problem. I did not re-install anything at this point.

Should I have done so?

On another thread I saw that I should have Microsoft Loopback adapter installed. This I did but the icon in the Windows XP start bar says that the Local Area Connection 3 has limited or no connectivity. I think this may be my problem but I don't know how to resolve the issue.

Does anyone have any ideas?

Hi Mark,

Just assign a static ip to loopback adapter such as 10.10.10.10 and enter the same ip and hostname in to c:\winnt\drivers\etc\hosts file

10.10.10.10 <hostname>

Hi Mark,

Clik the start button and run the b/m application server.

Programs/SAP Netwiever 7.0 ABAP Trial Version/NSP/Start Application Server

Then try to log on again.

Hope it helps
