i have resored the master and the knowledgemaster. I solved the second error, but I can't solve the error "unvalid databse notification":
This error also occurs, when I click a vault or a library in the ADMS Console...
another information: I can work with the Vault-Explorer. There is no problem! All Users are running...
I don't understand this!
I should make a whole restore of the backup. I think this should solve it, but this would not answer my question!
I want to find the reason for this error, to avoud it in future
