Hi
We have a software system which contains 10 drivers,
Mostly storage and filter drivers.
All the drivers run on top of W2K3 servers.
Is there an official guide\site\doc of what steps
do we need to do in order to convery our drivers so that they would
support Longhorn?
Thanks,
Michael

As I have stated in one of the other forum's you have asked this question
on, there is no official document on this. Search
http://www.microsoft.com/whdc/default.mspx the official Windows driver site
if you do not believe me.

Now, the customers I know have found that most WDM drivers move with no
change. If you are talking file system filters yes there are new requests
for things like transactions which first showed up in Vista. If you are
talking storage mini-ports there are some additional capabilities.

Are legacy FS filters still alive in Longhorn?

Max, AFAIK yes they are still allowed. Minifilters are nice in some ways
but there are definitely cases I would not use them due their limitations.
Things like the inability to get at the original request, and the
inconsistent set of functions for sending requests make them far from the
final solutution IMHO.
