After deploying CU4 I attempt to run the Install-CSDatabase -Update and receive error :
Install-CsDatabase :
Command execution failed: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I suspect I have a permissions problem related to the SQL databases.
Can someone clairfy exact permision I need on the SQL server/database in order to perform this funtion. Do they need to be exactly the same as if I were creating the database new? I don't manage the SQL servers so will need an very specific set of requirements to present to them in order to request the accesss.
As well, we have a pool of 6 Front end servers and 2 directors, should these servers (services and W3svc) be stopped during this process?
