Hello,
this is a desperate cry for help, i'm ready to hang myself (figure of speach) 
After upgrading all my vsphere components to the latest 5.x version (coming from 5.0) I installed the view connection server en security server as last components.
The view conenction server pointed me to the fact I have to setup certificates.
I've been follwing all steps, detail after detail from this KB:
Implementing CA signed SSL certificates with vSphere 5.x (2034833)
I have setup a AD CA integrated with the AD, made the needed changes to the template for key usage, made the certs, checked the certs, followed the steps to enroll the certs in the SSO
Al fine, all ok....
I'm at the point of Replace the vCenter Server 5.x certificates.:
I did wat is asked and it goes wrong at the point where i'm asked to login to the MOB. (AND I found out that I locked myself out of the vcenter)
So without reloading the sslcert in the MOB, the isregtools is not ending with code:
0
0
... it ends with
9
9
I stopped here to make sure that I do not encrypt my db with the wrong cert.
I edited the VPX-ACCES table and added local credentials, nothing works...
How do I proceed? 
I have to get all up and running by tuesday or we can't use our pc rooms on faculty :/
Desperate regards
John
