Does Microsoft's database run on DNS?

[pavel_lishin]

I wonder if every machine stores the entire catalog, and periodically syncs.

I assume on limited connections, it will never sync, meaning if you use a latop tethered to your cell-phone, you will see the windows-appstore of 1984. (any old date would have done, but this one rhymed)

Even DNS only takes 5 mins tops

When you talk about DNS propagation you have to take cache into account. You could set TTL that low (even if you do, some will ignore it) but normally it's a lot longer so you often get times like 24-48 hours for complete propagation.
