Strange issue with Minim on WHS2011

[Mick]

Hi Simon - I installed Minim Server (and java) on my HP Microserver last night. It installed ok, scanned all my music then showed green.
Now, here's the thing - I can't see the server on the network. I have two other media servers running on the HP box, and I also have a windows script file that scans for media servers.
If I run the script on another PC on the network I only see Asset and the new Linn mediaserver.
If, however, I run the script locally on the server I see all three mediaservers.
Firewall problems, possibly? I'll have a play tonight but wondered if you could think of anything off the top of your head.

Thanks

Mick
