SOS Problem with GUI login

[Former Member]

Please answer me as fast as you can because I have the following serious problem:

I had install the SAP WEB AS 6.10 (and SAPDB) test version which I took it from the book ABAP OPJECTS THE OFFICIAL REFERENCE. Unfortunatelly, it did not work well when I was off line of the network of my company, I also installed the network adapter of MS LOOPBACK (as the instructions are saying) but again I couldn't login, so I uninstall from my PC the SAP WEB AS. Next day when I went to my company I could not logon to SAP and the error message is: SERVICE 'SAPDP00' UNKNOWN. I check the fileservice which is under the directory C:\WINNT\SYSTEM32\DRIVERS\ETC and there is a line with SAPDP00 3200/tcp. I reinstall GUI 7 times but the problem still exists.

Well I hope that I will find a solution during weekend because if not I will forced to format my pc and reinstall all my aplication, sth which is very painfull.

My pc is working with WinXP SP1.

The error details are:

service 'sapdp00' unknown

This is for WebAS preview installations. Please issue an OSS message on service marketplace for your problem.

Finally I found what cause this problem and the temporary solution plus the permanent one.

My PC was hit by a virus (new version of QHOSTS-1 see at the end) which is changing the registry file HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

"DatabasePath"= %SystemRoot%\nsdb

So it is creating a host file under C:\WINNT\NSDB which it put it to the registry.

So the permanent solution is to change the Registry.

The temporary one is to run the following command from the dos:

sapgui /H/<address of the SAP server>/S/3200.
