Learn about using named streams over SMB connections in this advanced article.
Named streams are used to store Mac OS X extended attributes and can be leveraged to avoid using AppleDouble files to store the data fork and the resource fork of legacy Mac files.
Mac OS X Server v10.5 and v10.6, as well as many Network Attached Storage (NAS) devices, support named streams when you connect to them via SMB. 
Microsoft Windows servers with NTFS-formatted hard drives also support named streams when you connect to them via SMB; named streams are called "Alternate Data Streams" in Windows.
Mac OS X v10.5 and v10.6 clients automatically enable named streams support when they have a SMB connection to a Mac OS X Server v10.5 or v10.6-based server. 
Mac OS X v10.6 clients automatically enable named streams over SMB when the NAS or Windows server claims to support it.  See below for details about how to activate Mac OS X v10.5 client support of named streams over SMB connections to a NAS or Windows server.
You can enable named streams in three different ways, as described below.

This article explains how to set a custom umask in Mac OS X v10.5.3 and later.

Every file or folder has permissions associated with it. When you create a file or folder, the umask setting determines these permissions. The permissions on a file can be represented by a number with three digits of 0-7. When you create a file, the umask value is subtracted from a default value (usually 666 for files, 777 for folders)  to determine the permissions on the new file or folder. For example, the default umask of 022 results in permissions of 644 on new files and 755 on new folders: groups and other users can read the files and traverse the folders, but only the owner can make changes. For more information on permissions and their numerical representation, see this article.

When you create a file, the umask value is subtracted from this maximum permissions value to determine the permissions on the new file or folder. For example, the default umask of 022 results in permissions of 755 on new files or folders: the owner has full access, while the group and others can read and execute, but not write to the file.

System administrators may wish to set more or less restrictive umasks for their users. There are several different places in which a umask can be set, each affecting different applications.

The Multicast DNS feature of Bonjour allows devices on a local network to connect to each other without a separate DNS server by using the ".local" domain, as described in this article.
This advanced article explains how to make your Mac look up host names ending in ".local" using both Multicast DNS and standard Unicast DNS using the name servers specified in the Network pane of System Preferences.
Some private networks also use ".local" domains for hosts registered with their internal DNS server, even though it is not a valid top-level domain on the public Internet. If your Mac is connected to such a network, you may want it to look up host names that end in ".local" by using Unicast DNS to speak to a DNS server, the same way that it looks up host names such as "www.apple.com" on the Internet.

If you’re trying to install Mac OS X on a hard disk that you’ve connected to your Intel-based Mac, you may see this alert in Installer and be unable to select the disk for installation:
"You cannot install Mac OS X on this volume. Mac OS X cannot start up from this volume."

The Mac OS X installer prevents you from installing on to a disk that uses a non-native partition scheme (or to any volumes on that disk). PowerPC-based Macs and Intel-based Macs have different native partition schemes (see additional information below).
