Microsoft Cluster Server

This section lists required access permissions to install and monitor your environments and the required communication ports. Verify that the listed communication ports are open.

AIM Installation

Requires Windows System Administrator privileges on the AIM host.

Monitoring

Requires a domain administrator account or a cluster node local account. If a domain user is used, it must be in the domain administrators group. If a cluster node local account is used, the user must be a member of the administrators group.

Important! Set up the same cluster node local credentials on all nodes. If the cluster service is moved to a different node and the node has different credentials, the AIM is unable to connect.

Communication Port

Windows RPC Endpoint Mapper Port: 135

DCOM/WMI Port: dynamically assigned during RPC Endpoint negotiation

For more information, see The default dynamic port range for TCP/IP.
