Appears when I test the patch insatller Windows Update for ZENworks 8.1 (11 SP3), I get the following message on the ZCC:
The wizard can not continue for the following reason:
Error Could not complete your request for the following reason: ZENworks could not detect if the ZENworks Server or the ZENworks Loader services are running on one or more Primary Servers. You need to stop the services before proceeding with the System Update. Check the logs for more details.
Yet I have stopped services on my 2nd primary server. and I do not see anything special in the logs
Are that someone has already been confronted with the bp?

PS: Sorry for my English rather approximate
