Hi,
What you need to do is:
1. Set login/no_automatic_user_sapstar = 0 in default profile or instance profile.
2. Delete user master data for sap* in table usr02 with database tools. run sql:delete from sapsr3.usr02 where bname='SAP*' and mandt='001'
3. Restart system.
4. Logon on with 001/SAP*/PASS via SAPGUI.
5. Recreate administrator user with SU01.
6. Remove login/no_automatic_user_sapstar = 0 in profile and restart SAP system.
After that you will be able to use the user created in step 5 to logon to the client.
Thanks.
Jim
