The BlackBerry Monitoring Service has been installed on a server that has two network interface cards (NICs).

Workaround 1

Install the BlackBerry Monitoring Service onto a server that does not have more than one NIC.

Workaround 2

Warning: The following procedure involves modifying the computer registry. This can cause substantial damage to the Windows® operating system. Document and back up the registry entries prior to implementing any changes.

Complete the following steps:

1. Disable IPv6 on the server hosting the BlackBerry Monitoring Service.
2. Configure the BlackBerry Monitoring Service to use the IPv4 protocol stack:
   1. For a 32-bit Windows Server, go to HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Procrun 2.0\BBMonitoringConsole\Parameters\Java
   2. For a 64-bit Windows Server, go to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\BBMonitoringConsole\Parameters\Java
3. Modify the Options value and add the line: Djava.net.preferIPv4Stack=true
4. Restart the BlackBerry Monitoring Services.
