in beta3 i mapped a network drive from the windows VM to allow file integration between guest and host OS's. only about a week after i set it up, in beta3 and beta4, it can no longer connect to the macbook because "the specified network name is no longer available. i have file sharing activated within osx, with the user account enabled, and am able to connect to other windows machines from my windows VM, but for some reason i can no longer map a drive from my guest os to my host, any ideas?
