As posted previously, I have installed the new OneCare beta on my Vista RC1 machine. Now I found that everything’s not perfect with it: it kills connectivity with my Windows Mobile device, which had previously been working nicely. I’ve spent a moment looking around for relevant configuration opportunities and found none. I also looked for log files that might give more insight into the problem, but found none of those either. It’s possible to get a log file out of OneCare, but that doesn’t contain anything similar to a “normal” firewall logfile entry. Basically it seems like OneCare protects the virtual network adapter for the Windows Mobile device by letting nothing through, but at the same time it never mentions the fact to the user, nor does it let the user do anything about it. I hope that’s not the whole story, but I can’t spend much more time right now looking into it.

Update: word has reached me out of Microsoft that this is a bug related to the combination of various beta versions on my system. It’s being “looked into” – I’m looking forward to the result.
