Solution candidate:
Uncheck/disable IPv6 and Link Layer Discovery protocols from network connection properties.
Some guides instruct to change certain related registry values as well, but to me this does not seem necessary for solving the problem.
I just flew a few sorties in the MA with no mentionable warping after doing this.
Vista has by default these features enabled and they have to be manually disabled.
It has been said that MS was too hasty enabling IPv6. This may be the case.
