I've been running a Rio 10mbps phone line connection through my house for the last 4 years - relatively few problems. Recently I upgraded all the computers in my house to WinXP Pro SP2.

Since then no matter what machine (I have 3) I try to run ARMGR on I can't get a blue note. I also have two 3com cards and I've tried both.

I've got 3 Rio Receivers running off the house phone line into the 3com NIC.

In XP the connection for the 3com NIC keeps reading "A Network Cable is Unplugged" - but on 3 machines it says the same thing, all plugged into different telephone jacks.

Here's what I've tried:

1. Obviously setting up clean installs on 3 machines, even swapping between the 2 NIC cards to see if one was bad.
2. Turned off Windows Firewall

I'm not running through a router (never have) - just over the existing phone line. Again, this thing has been running in my house for 4 years, so this isn't the first time I've used it!

Now the last thing - on TWO seperate occasions in the process of trying this over and over, I've seen one unit show up in the ARMGR but no blue note. And it didn't actually play music to the unit, it just showed up in the ARMGR for a moment.

Any suggestions? There has to be some configuraiton problem here.
