Could you explain this point :

Did you reinstall your Win2000 O.S or not ?

Another point is if you changed the CPU then the problem might come from a license issue.Your hardware key might have changed, therefore you may need to reinstall a new license key.

You can also have a look at the services file ( under windows\system32\drivers\etc ) and see if the sap services are defined.

Let me know.
Steve.

regards.

Hi,

1. What do you mean by "repairing" the O.S ?
Can you post what you exactly did ?

2.Is the SAP instance started and on-line on your SAP server ?
This can be viewed using the SAP MMC.

3.Could you log on the SAP box as user <SID>adm, open a command prompt and post the result of commands :

saplicense -get

saplicense -show

4. Are you trying to logon from the SAP server itself or from a remote computer ?

If you try from a remote computer, verify that the sapdp00 service is defined also in the services file of the computer you try to log from.

Answers to your question :

- Reinstalling the OS will obviously damage the sap Installation as you will delete the SAP installation regitry keys.

- If it is a license issue you will have to ask SAP a new license key based on the new hardware key.

HTH,
