Hello Shahan,
it seems this Discussion is still in the Software Support Space, and only a reference has been shown in the NetWeaver AS Space...
Anyway, to answer your question:
- on OS level go to \user\sap\SYS\profile
- pick an instance you will use, and open its profile file.
- add the following line at the bottom of the file: login/no_automatic_user_sapstart = 0
- restart the entire system from MC (or any other administrative consol you use)
- adjust the SAP Logon Pad so you will logon the instance which you have adjusted now
- logon with user SAP* and password pass (or PASS, I can't recall which is correct now).
(Also, I'm not 100% sure, but I believe client 000 or 001 needs to be used...)
Best regards,
Laszlo
