Installation was successfully but cant start the portal
I download the SAP Portal 7 trial version and installed it in typical option on Win XP. During the install it was asked to put the master password. The installation was successfully finished. Trying to start the server from the administration console it was asked to authenticate (put the username and password.) After typing of the credential data I get in a message box: "invalid credential, start failed: 2" and the start of the server fail. I retyped and even reinstall the Portal two times to be sure that I do not make a mistake but each time I get the same error!
I installed it later again and choosed custom installation option and step by step, put all necessary passwords and installation was successfully. But the result was the same and I get the error again!
Please help to to get the portal a start
