Add a Mac to your Windows Network (Part II)

Even though you may have been
sharing files between your Windows computers for ages, knowing how to network
and share on Mac computers may not be obvious. The first half of
this two-part tutorial series
explained how to enable Windows Sharing and
set the Workgroup in Mac OS X Leopard and Tiger. It also talked readers through
how to configure the firewall in Mac OS and Windows to allow this type of
sharing. Part II discusses exactly how to share files and folders on your Apple
computers, in addition to giving tips and tricks on the co-existence of
Windows-based PCs and Macs on your network.

Sharing in Mac OS X

Individual folders in Mac OS X
Tiger can’t be shared on the network. However, the personal folders (Desktop,
Documents, Music, Pictures, etc.) of each Mac account are always shared by
default with computers on the network that have used the correct username and
password to login. Plus the Public and Sites folder of each Mac account are, by
default, shared among all computers and users on the network.


To share files on a network in
Tiger, files and folders can be copied or dragged into personal folders of Mac
accounts (to be shared with others on the network logged into the Mac computer
with that Mac account’s credentials) or dragged into the Public or Sites folders
(to be shared with all other computers and users on the network).


Tip: The Public and Sites folder of
each Mac Tiger account may not appear automatically when viewing a Mac
computer’s shared resources from other Windows-based computers. However, it
should work by accessing the folder manually by its UNC path, for example
entering MacComputerNameMacTigerShortName into the address bar in Windows.


Sharing in Mac OS X

Unlike Tiger, Leopard allows
specific folders to be shared on the network; here’s one way to go about doing


  1. Click
    the Apple icon on the menu bar.
  2. Click
    System Preferences.
  3. In
    the System Preferences window, click the Sharing icon.
  4. On
    the Sharing window, select the File
  5. Under
    the Shared Folders list, click the plus sign, browse to and
    select the folder, and click Add.
  6. Once
    a folder is added, configure the permission settings as desired in the Users
    list box.


Tip: Sharing folders in Leopard is
similar to how you do it in Windows: right-click a folder, choose Get Info,
select the Shared Folder checkbox, and specify the permissions on the bottom of
the window.


Note: The personal folders (Desktop,
Documents, Music, Pictures, etc.) of Mac accounts are only accessible from other
computers on the network if a particular Mac account’s credentials are entered
when the shared Mac computer is accessed. This is even the case when a Mac
Administrator account is used in Windows when trying to access a Mac computer;
the entire Mac system is shared, except the personal folders of the other Mac


Matching account credentials on Mac and

It’s best to set the same exact
account names and passwords for users across all computers on the network. This
is because when a Mac computer is accessed from Windows, Windows first checks to
see if an account on the Mac computer matches its account name and password. If
a match is found, Windows automatically uses its login credentials to connect to
the Mac computer—saving the user time by eliminating the need to input login
credentials. This same process applies when accessing Windows computers from
Macs, or in Windows-to-Windows scenarios.


This feature of Windows and Mac
operating systems, however, can become a pain (more so when using Windows) when
a user wants to connect to a computer’s shared resources using an account that
differs from the Windows or Mac account he or she is currently logged into.


In Mac OS X Leopard, switching
the account is very easy. When browsing the contents of a computer on the
network it displays which account is being used. Clicking the Disconnect button
(see below) logs the user out of the current username and password. If the user
clicks the Connect As… button, a login dialog box will appear and a different
username and password can be used.

In Mac OS X Tiger changing the
account used to log into computers on the network is possible by clicking the
Authenticate Again button on the dialog box that’s shown when connecting to a
shared resource (see below).

In Windows Vista and XP, however,
it’s a bit more difficult to change which username and password are used to log
in to computers (Macs or other PCs) on the network. The first time a user
connects to a computer’s shared resources, she will be prompted to enter a
username and password that matches an account on the remote that has been
authorized to access or write to the shared folder or drive. (But if the user
account she is using matches an authorized account, the user won’t even be
prompted and Windows will use her account username and password.) Once a
username and password is entered and the Remember My Password option is checked,
the user probably won’t be prompted again to login, and the account credentials
will be saved. (In the case where a user’s username and password matched, she
won’t be prompted at all).


In Windows XP and Vista, you can
change the username and password for particular computers on the network by
clicking a link from your User Account window by following these steps:


  1. Click
    Start>Control Panel.
  2. In
    the Control Panel window, click the User
    Accounts (in XP)  or User Accounts and Family Safety (in Vista)
    category, and then click User
  3. In
    XP, click the Windows account you’re
    currently logged into and
    on the next screen under the Related Tasks pane on the left side of the
    account settings window, click the Manage my network passwords link. In
    Vista, click the Manage your network passwords link
    . The
    Stored User Names and Passwords dialog box should appear.
  4. If
    you already see an entry for the computer on the network you want to change the
    login account for (listed as the Computer Name in the list box), select it and
    click the Remove button; otherwise continue with the next step.
  5. Click
    the Add button. The Logon
    Information Properties dialog box (in XP) should appear or
    Stored Credentials Properties (in Vista)
  6. In
    the Server field (in XP) or
    Log on to (Vista), enter the Computer Name of the computer on
    the network you want to change the login account for.
  7. In
    the User name field, enter a Mac (or
    Windows) account name that’s authorized to access the computer on the network,
    using the appropriate format; for example computernameaccoutname. If entering a Mac OS X
    Leopard account name, enter the actual Name of the account (not the Short Name)
    even if spaces are included. But if entering a Mac OS X Tiger account name,
    enter the Short Name for the account.
  8. In
    the Password field, enter the
    password for the Mac (or Windows) account that’s being used.
  9. In
    Vista, click the A Windows logon
    radio button.

  10. Click
  11. You
    may have to Log Out of your Windows account and log back in for the changes to
    take place.


Tip: When changing the accounts used to
log in to network computers, think about any mapped network drives or offline
files you’ve set up. If the new account specified for log in doesn’t have the
necessary privileges to access folders or drives that are mapped as network
drives or setup as offline files, delays at boot and errors may occur.


Wrapping it up

Now that you’ve gone through this
tutorial, and
the previous one
, you should be able to share files and printers between
your Macs and PCs. You’ll also know some tricks to help yourself along the way.
