On a wireless network, the HD1000 sees shares on a Windows XP Media Center SP2 box, but not on two different XP Home Edition boxes. (It's recognized the PC's - just doesn't find any shares).
All three computers can see each others shared volumes. What's weird is that the Guest account on the MC box isn't enabled, but it still sees the share on that system. But on the XP Home boxes, even with a login name/password specified, it doesn't.
All these are on a home wireless network.
It's an older HD1000 that's been on the shelf for a while, firmware 1.5.18. Might this be addressed by upgrading the firmware, and if so, where can I find it and instructions, as I can't find the manual.
