The installation is failing on the "Check DDIC Password" phase with the following message.

" Test logon to SAP System PRD failed.


     SOLUTION : Make sure that the system is started,that the user DDIC exists and that the password of user DDIC is correct


We have verifying the password is correct and the system is indeed up.

We however cannot logon to the system SAPGUI issue the following message :

"SAP System Message:

We have tried to redo the export and import several times but still experience the same error.All prerequisites activities have been performed on the source system and target system.We have upgraded the kernel on the target system to the same level as the source system

Your assistance would be greatly appreciated .

I had similar issue while installing system on windows 2008 R2.

For system installation / System copy of windows 2008, the original kernel cannot be used.  Refer to these notes and do the kernel upgrade. It should work.
