Thanks @jimbo. I will work through your suggestions when I get a chance. I should note that when I installed PPBE around a week ago it was connecting to the UPS management pages and then it suddenly stopped with the connection errors. I can't recall fiddling with anything network related so this is kind of odd.

On a side note what does the 3052/agent/ part of localhost mean and how does that open the UPS management software in the browser?
