Right so I stream media to a PS3. I haven't made any major changes to windows lately that I can think of, but yesterday did install an update from MS - Core XML Services service pack 2.
Now my WMP media server/sharer thing has stopped working. PS3 reports 'no media servers found'. Verified connection between then, rebooted, set all WMP related services to 'Automatic' and made sure they were running. When I try to go into media sharing settings on WMP, it brings up an error dialogue about some kind of missing service or component, but as far as I can see, everything should be working.
Scoured the internet for an answer, even the MS knowledge base, which led me round in circles with dead links (as is often the case).
Checked registry keys as well, and file permissions for WMP database and program dirs.
Anybody else run into this, or know a fix?
