### 8.2.2. Optional/Additional Steps

#### Specifying the RSM Windows Domain

If the cluster submit host is running on Windows, you will have specified the RSM Windows domain name during the EKM server installation. If for some reason you need to edit this value after installation, you can do so in the ekm.xml file by editing the `rsmWindowsDomain` setting. For details see Specifying Remote Process Policies (<remoteProcess>).

#### Specifying Permissions on Queues

By default, all users will have access to all RSM queues. If desired, you can restrict certain users from submitting jobs to a queue by setting permissions on the queue. (See Editing Permissions in the EKM User’s Guide.)

#### Dealing with Multiple Network Interface Cards (NICs)

When jobs are submitted from EKM, a servo process is launched on the cluster submit host. The servo process enables communication to be established between the EKM server and the submit host. By default, the servo process obtains an IP address from the environment in which it is running, and registers it with EKM. This can pose a problem if multiple NICs are being used on the submit host, and may result in job submission errors.

When multiple NICs are used on the submit host, you can avoid errors by defining an `EKM_SERVO_IP_ADDRESS` environment variable on the cluster submit host (where the servo process is launched). This variable enables you to control which IP address will be used by EKM to connect to the servo process. For its value, specify the IP address of a NIC with which EKM can communicate. You can obtain this address from your IT administrator.

See also: Configuring a Computer with Multiple Network Interface Cards (NICs) in the RSM User's Guide.

#### Dealing with Firewalls

If the cluster submit host has firewalls set up to block certain ports, users may encounter errors when submitting jobs to EKM from Workbench, or running server-mode jobs from EKM.

To prevent such errors, ensure that all ports on the cluster submit host are visible from the EKM server.

If jobs are being submitted to an advanced ANSYS RSM Cluster (ARC), refer also to Dealing with a Firewall in a Multi-Node ANSYS RSM Cluster (ARC) in the RSM User's Guide.
