Administration Guide Changing the name of the BlackBerry Administration Service pool If you do not install both components on each computer in the pool and you try to access one of the URLs using the pool name, the web browser might display an HTTP 404 error message. The HTTP 404 error message occurs when the web browser tries to connect to a computer in the pool that you did not install the component on that you are trying to access. For example, you can install the BlackBerry Administration Service on two of the computers in the pool and the BlackBerry Web Desktop Manager on two other computers in the pool. To make sure that the web browser does not display HTTP 404 error messages, you can choose one of the following options: • You can create separate pools within the BlackBerry Administration Service pool for the BlackBerry Administration Service and the BlackBerry Web Desktop Manager. You can provide your organization's administrators and BlackBerry device users with URLs that include the specific pool names. • You can provide administrators and users in your organization's environment with URLs that include the FQDNs of the computers that you installed the BlackBerry Administration Service or BlackBerry Web Desktop Manager on (for example, https:///webconsole/login or https:/// webdesktop/login). Configure the BlackBerry Administration Service instances in a pool to communicate across network subnets The instances in the BlackBerry® Administration Service pool use multicast UDP to communicate with each other. If the BlackBerry Administration Service instances are located in different network subnets and your organization's network configuration does not permit multicast UDP across the network subnets, you must configure the BlackBerry Administration Service instances to use TCP to communicate with each other. For example, if your organization uses a UDP peer-to-peer firewall filter, you must configure the BlackBerry Administration Service instances to use TCP to communicate across the network subnets. 1. Make sure that no BlackBerry Administration Service instance is in the process of restarting. 2. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > BlackBerry Administration Service. 3. Click Edit component. 4. In the BlackBerry Administration Service pool drop-down list, click TCP with TCP PING. 5. Click Save all. 6. Restart the BlackBerry Administration Service instances.

If you do not install both components on each computer in the pool and you try to access one of the URLs using the
pool name, the web browser might display an HTTP 404 error message. The HTTP 404 error message occurs when
the web browser tries to connect to a computer in the pool that you did not install the component on that you are
trying to access. For example, you can install the BlackBerry Administration Service on two of the computers in the
pool and the BlackBerry Web Desktop Manager on two other computers in the pool.
To make sure that the web browser does not display HTTP 404 error messages, you can choose one of the following
options:
You can create separate pools within the BlackBerry Administration Service pool for the BlackBerry
Administration Service and the BlackBerry Web Desktop Manager. You can provide your organization's
administrators and BlackBerry device users with URLs that include the specific pool names.
You can provide administrators and users in your organization's environment with URLs that include the FQDNs
of the computers that you installed the BlackBerry Administration Service or BlackBerry Web Desktop Manager
on (for example, https://
<FQDN_of_computer>
/webconsole/login or https://
<FQDN_of_computer>
/
webdesktop/login).
Configure the BlackBerry Administration Service instances in a pool to
communicate across network subnets
The instances in the BlackBerry® Administration Service pool use multicast UDP to communicate with each other. If
the BlackBerry Administration Service instances are located in different network subnets and your organization's
network configuration does not permit multicast UDP across the network subnets, you must configure the BlackBerry
Administration Service instances to use TCP to communicate with each other. For example, if your organization uses
a UDP peer-to-peer firewall filter, you must configure the BlackBerry Administration Service instances to use TCP to
communicate across the network subnets.
