9. Software installation will now begin. The following dialog box will display a percentage complete
graph during this process.
10. The following dialog box will be displayed upon completing software installation. Click Finish to
clear the dialog box. There is no need to reboot the server. If you are installing Services for UNIX
version 3.0 continue with the next step.
11. If you are installing Services for UNIX version 3.0, a change must be made to the Registry to turn
on Write Caching.
Note that this change was implemented by Microsoft in order to fully comply with the NFS
specification. When an NFS client receives an acknowledgement that data has been written, the
specification states that that data must have been committed to stable storage. When write caching is
turned on, Server for NFS acknowledges upon receiving the data in the cache. In our application, it is
doubtful that there will be much difference if the server cannot write the cache data or just stops
accepting data for whatever reason; the result will still be a recording that terminated too early or an
unfinished copy operation. The write cache greatly improves efficiency of recording operations.
WARNING: Making changes to the registry is dangerous and mistakes can result in having to
reinstall the operating system in extreme cases. Use Backup to make an emergency rescue disk that
includes a copy of the registry before attempting registry modifications.
