Right, pre-releases like RC and beta versions are not for production use.
Windows Server 2008 R2 is yet still in beta or RC state - but server
2008 is production ready and I think aobut "why use 2008 if 2008 R2 will
be available soon". Translation of system will take some more time at all.

Windows 7 was official released (at least to MSDN and MSDNAA and system
builders). The image in MSDNAA is the official release version of
Windows 7 - I do not see any reason why not deploy it in a production
enviroment (after testing it).

The streams strikes back again. Did not know Windows 7 depending on
streams in filesystem.
So far I determined some small problems only.
Most annoying one is: some .exe does not run out of OpenAFS space, some
others do. Alternative streams could be a good explanation to this

Btw, any plans about multiple streams in OpenAFS? I know that point was
in discussion, once.

Thank you. That was one of the points I wanted to know ahead of testing
it - I guess you saved me some hour of work.

With all this in mind - I guess I set up a second public win7 test
system for our users and play with a testing ground with win 2008
server. After Win 2008 R2 has gone released - switch AD over and
afterwards maybe Win7.
