I have a Windows Vista 64 bit system (A) which is hosting a Windows XP 32 bit virtual machine (B).
I need to call a web page hosted on A, from B (IIS 7). B can't access A. I get a "currently unavailable" error message. B can ping A. B can map a drive on A. B can't browse a web page on A.
I can do the reverse (Call B from A), but that doesn't do me any good.
I imagine it's a security or firewall issue, but I'm not sure how to resolve it.
