I only see the Ping Response not received when I either reboot the server and it first comes back online and/or our connectivity to the internet drops.
The last error can likely be remedied by opening BlackBerry Server Configuration then clicking on the BlackBerry Router tab (for the description not found part not the actual error).
The same goes for any similar errors, depending on their name. BESAlert is one, which the tab is located under BlackBerry Server Properties in the BlackBerry Management MMC. Why these are not registered when you install the server, I do not know. It seems to be bad coding when you receive errors that have no description for fresh installs, and the fix it to initiate a properties tab in order to install/register a description/DLL.
But I think your issue is likely one relating to your particular network.
In the beginning the Universe was created. This has made a lot of people very angry and is widely regarded as a bad move.
