Hi Chris / Dalma,
The issue is with the C:\Windows\System32\drivers\etc\services entries.
Do add your samps<SID> port/TCP entris.
also the all relevant entries.
sapdp00 3200/tcp
This should resolve the issue.
also Do verify your instance number and maintain the right Instance number in SAP GUI. Let us know if this helps.
Regards,
Ram

i can't figure why sap gui is trying to connect to 127.0.0.1 ???
and after a while it works without any modification... very strange no? but annoying!
if i do not use logon group and connect directly it works but it is not what i need to do.
any idea?
regards

hello,
thanks but configuration of logon groups is very straightforward...
my logon group contains my two application servers.
what else do i have to check?

I think I have gone thru all the logs but could not resolve the issue.
I appreciate any help on this,

I tried to go thru the thread. I did not find any clue as why only server connectivity is failing. ABAP trial version is running fine and the NW trial version is working fine too. These run without crashing. I did a lot of customizing on the portal but dont see any issues except the System Connectivity. Like I mentioned I did UME configuration to point to NSP ABAP instance and I can log into the portal with user credentials that I use to login to ABAP. I can launch webgui etc without any issues.

Hi..
i strongly beleive , After a client copy you are not able to connect sounds, You oraarch directory is full and database is not accepting any incoming requests from application. (or) Dispatcher is stopped.
if you are sure - you have done no changes on server end except using SAPGUI i.e. client copy - The only reason i feel - ORAARCH is FULL.
if it is not the reason
======
can you ping the server ?? if yes
As ora<SID> user Check - is db is up or not ??
As ora<SID> user Check - listener status ??
As <SID>adm user check - "R3trans -d" what is the return code ??
if return code is 0 no issues with DB connection ??
if return code other than "0" enclose trans.log file (it will be created in directory where "R3trans -d" executed.
also enclose dev_disp trace file from work directory.
if this answers - Please mark it as answered.

If the ping do not works pl check out for network problems.

Hi,
insert into the file C:WindowsSystem32driversetcservices the item:

Perhaps you have to reboot the server.

Hello. are your database Oracle? If yes the version are? Dependent on version you can use SAPDBA or Brtools, or both in one time.
http://help.sap.com/saphelp_47x200/helpdata/en/3e/5e123b4a4eca10e10000000a114084/content.htm
Try to check START>RUN>CMD-->BRTOOLS (before login in your OS under SIDadm user).
Try to check dev_w0 file in "work" directory.

After portal copy "connection refused" for SAP transactions

Hi.
We made a system copy of Portal and executed all follow up tasks.
We already changed systems alias properties and tested connections.
All is working except SAP transactions functionality.
When we try to use, we always get message:
patner '10.0.0.132:sapdp00' not reached.
WSAECONNREFUSED: Connection refused.
Curious thing is: the system we are trying to reach use system number 10 (not 00).
We look for this parameter value in every part, on portal configuration, and all seems to be perfect.
We are without options, and we don't know what is missing/wrong.
May anyone help us to find this solution?
Best regards.
Vreeswijk

Hi,
From portal on which backend system you are running transaction and Is portal able to reach that system ?
Thanks

Netweaver trial version - Connection refused

Hi.
When I log into my sap gui for windows 720 trial version - i am not able to connect to the server. the following error message appears.
partner : 127.0.0.1:sapdp00 not reached.
WSAECONNREFUSED : connection refused
pl advice as how to disable the firewalls as i am using windows home premium os and norton antivirus and logon sucessfully.

Hi,
Check the following:
- In the SAP Management Console, is the system running(green).
- Have you installed the Loopback adapter
- Disabled Windows firewall via Control Panel -> System and security -> Firewall
- Also Norton might have its own firewall and blocking the SAP ports. Disable and retry.

I had not modified anything since I had installed it. All is by default. I believe that system id is J2E and system number is 00. In any case I have tried other possible values.

Also, I have no 'SAP Netweaver 2004s' item in Start menu, only MMC console. Maybe I should install something else?

Hi Ivan,
As you mentioned, it is possible to connect to <a href="http://localhost:50000">http://localhost:50000</a>. Go there and choose System Information. Log in and on the information page you will see the required message server port to connect to the system via Visual Studio.
As I wrote, there is no possibility to connect via SAP GUI.

Hello Ashish,
then you may need to check the router string carefully if it is correct. "connection refused" in your error message means, that either the program is not running and not listening to the port 3299 on the affected server, or connection data are wrong. Do you have a SAProuter trace and did SAProuter notice in the trace, that you are trying to connect to it?

Alwina
