I have purchased a promise NS2300 NAS. Problem I have is that the Java software for the NAS does not see the NAS. Even though I can access the folders via Network. I am wondering if the applet needs some form of port opening. Promise.com support are equally mystified.

The set-up is Windows Vista Home Prem SP1.

Netwoprk over power line from PC to Sky router.
CAT 6 cable from router to NAS.

NAS specific IP address

I have switched windows firewall offan dcompeltely reset the router but still no luck.
