Windows 7: Unsolvable networking issue

Folks,

Could it be I have (sadly) found a network issue which has defeated every Windows 7 expert community? I have posted my issue on every expert forum I can find, in total almost 1'000 views, but not one answer. Is this because my issue is too niche, or because the solution has in fact eluded the whole world? Or maybe I just wrote too much and p****d everyone off?

In a nutshell this time (you can read my prior posts if you want the whole soup-to-nuts version): on my network, the only computer which cannot network properly with our Macbook Pro is my Windows 7 Ultimate x64 machine (other W7x32Pro fine, XP fine). I am 99.9999% sure this is a setting and/or incompatibility with either Ultimate or 64-bit, since there are NO issues networking with XP or 32bitW7. And the W7x64 machine can see the Mac, but not the other way around.

Desperate now for help on this. Anyone got any ideas at all? I have tried all the Control Panel stuff listed on these forums, and I done the secpol mods (unless there are others I have not tried yet).



Thanks on the offchance anyone can solve this.
