Default WiFi to BES. 9700 DNS Cache causing problems

Please Login to Remove!

All of our WiFi capable Blackberrys are configured to use WiFi and connect to our wide area WiFi APs as well as the most common SSIDs on the common port 4101. It appears 5.0.0.348 doesn't clear the DNS Cache when roaming SSIDs controlled by different DNS Servers.

In short, if my 9700 boots at home it connects on WiFi and uses my ISP DNS, it then forms a connection to my office BES using bes2.xxxxxxx.com on ip address 216.76.xxx.xxx. When I get to work, the 9700 connects on WiFi to those APs which DNS routes bes2.xxxxxxx.com to IP address 10.1.8.201.

The 9700 shows 216.76.xxx.xxx as the location to my BES which will fail internally and then force all IP/BIS/BES requests out through the carrier and then back to my BES from the Internet on port 3101....Just like all other Blackberry phones and a method I dont want to use. I use the WiFi method as automatic failover in situations where my cell carrier is unavailable or the Blackberry Internet Service fails. Eitherway, we can still browse the web through my Blackberry Server as well as communicate via E-mail and PIN.

I just installed 5.0.0.351. I am at work now. So when I get home I can see if the problem has been fixed.

Anyone else having this problem?
