I can no longer view the Blackberry Administration service

I recently started a new job and we have two BES servers. One in Fort Lauderdale and one in Miami. I am told Fort Lauderdale is the primary and I can confirm this by going to the Blackberry Server Configuration Panel and under the Blackberry Server tab, I see the Miami server listed as STAND BY. My issue is with the Blackberry Adminstation Service. When I click this icon I get the standard "Internet Explorer Cannot display webpage" as if an IIS server is down. The URL is pointing to our Miami or Standby server and I am told that is the correct URL. I know this worked a couple weeks ago because one of my first days here I was told to go in and clean up a few users and I logged in with no problem. We did have an issue a few days ago with email and it ended up being DNS related. All that seems to be ok now and I can PING the FQDN of both Blackberry servers. Blackberries are working as of now but I know this will be an issue as soon as someone needs to be added or has a device issue. All advice on how I can get the Blackberry Administation service working again is welcome
