Getting exception PASSWORD_NOT_ALLOWED during sapinstall

Dear Experts,

I am now at step 31 of 36 "Restarting Instance";

I am getting an error stating "PASSWORD_NOT_ALLOWED".

When I reset the DDIC password to default of 19920706 and restart sapinst I receive the previous error of "Password Not Allowed". Then when I change the password for DDIC to something other than the default and restart sapinst I receive the error stating "Unable to Open RFC Connection ".

I would appreciate any suggestions?

Thanks & Best Regards,

Michael
