Cluster Domino Gateway does'nt work on cluster MSCS EV

Hello,

I Have the The Domino Server console logs the following error:

...NotifyDirectoryService Failed - [0x80040e14].

I have a MSC Scluster EV on W2K8R2SP1 with one cluster domino with Evhousekeeping functionnality installed on each node.

I read the discussion https://www-secure.symantec.com/connect/forums/high-availability-enterprise-vault-domino-gateway about the cluster MSCS Domino.

Should we always install a domino mscs cluster on a cluster mscs enterpise vault, or are there a specific configuration for the gateway operates domino cluster.

Thanks a lot
