Microsoft plans to increase Unix interoperability with the upcoming release of Windows server 2003 R2. MS plans to add support for a number of unix services like the Network File System (NFS) client, NFS Server, User/Name Mapping, Telnet Server & Client, Password Sync and NIS Server.
Can't say if this is Good news for Windows or Unix or maybe bad news for both !! But Microsoft sure is learning from its mistakes. Unix would now in one way or the other be present in all the current commercial OSs: OS X, BSD, Linux and now Windows. I remember a quote by one of the unix designers who when asked where do you see unix in 2020 has mentioned that he doesn't know where unix would be but it would still be called unix :)
