In order to effectively troubleshoot this issue, you need to understand how BES makes its SRP connection to the BlackBerry Infrastructure.

As per system requirments for BES5.0, it states that...

System requirements: Firewall

To install the BlackBerry® Enterprise Server, configure a firewall or proxy firewall with the following conditions:
• exclusive use of port 3101 to open and maintain an outbound, bidirectional TCP/IP connection to an external server
• support for resolving Internet addresses that use DNS
• for proxy firewalls, transparency of the proxy server

You may like to check your network conditions on the computer hosting the BES.
