Something to think about.
If you intended using Z: drive mapping to the NETLOGON directory, you will experience problems in the future with unusual high traffic to the site. Peaking around 95% - 100% This is because directory replication. With client pc's having the Z: drive mapped, it creates dirsync to fail because files are open or inuse. The server misses it dirsync cycle and inturn login scripts and batch files in the NETLOGON directory are outdated. Then you will start getting errors, which seems to be something that should be in XFILES. On remote sites using 64k links or dialup facilities, 100% utilization is a killer forcing links to be unusable for 5 - 10 minutes, every 1 - 2 hours depending on what needs to be replicated and how big your network is.

To get around this make sure you delete the Z: drive mapping when you finish, or even better use Paul Moxey solution ( see above )
