When adding a new StorageServer or MirrorServer to a Storage Platform the following error is displayed:
Unable to load SSL certificate: The specified network password is not correct
The security levels on Server 2008 and Server 2003 are different. When an AccountServer on 2008 tries to distribute a new certificate to a new SS on Server 2003 it fails because Server 2003 cannot open the certificate.
Either use a the same Operating System for both the AS and SS or use SP V6.0.2.x or higher.
(Note that an AS on 2003 will be able to talk to a SS on 2008 but not vice versa)
