Problem during installation. sld registration

Hello,

I'm installing a SAP ERP 2005 system. The installation is stopped when sapinst try to register the system in the SLD. (SLD on solution manager 4.0).

Here is the errors from the log:

FRF-0007 (Unable to open RFC connection)

MUT-03025 (Name or password is incorrect).

Connection to http://hostname:50000/sld/admin with user J2EE_ADMIN is ok.

Any ideas?

Does problem come from a bad password entered in sapinst at the beginning?

Could anyone tell me how to force sapinst to enter new sld informations again without restarting all the installation? Note that I've exactly the same problem with another similar installation which also use the same SLD.

Many thanks for your support!
