I put my system to Stack 12. After that, SMD and Self Diagnosis not working any more. Here the message:
URL http://sv030488.myco-group.com:8001/sap/bc/webdynpro/sap/dswp_sd_self_diagnosis call was terminated because the corresponding service is not available.
The termination occurred in system MMS with error code 403 and for the reason Forbidden.
SM59 connection test shows:
ERROR: program WEBADMIN not registered
how to register ??
