9Alternatives include two free implementations of AppleTalk for several kinds of UNIX machines and several more
10commercial ones. These products allow you to run file services and print services natively to Macintosh
11users, with no additional support required on the Macintosh. The two free implementations are <a class="ulink" href="http://www.umich.edu/~rsug/netatalk/" target="_top">Netatalk</a> and <a class="ulink" href="http://www.cs.mu.oz.au/appletalk/atalk.html" target="_top">CAP</a>.

25 can optionally add IP names and addresses of these servers

28 may need to download an update for <code class="constant">IBM Peer</code> to bring it on

64Windows for Workgroups does a lousy job with passwords. When you change passwords on either
65the UNIX box or the PC, the safest thing to do is delete the .pwl files in the Windows
66directory. The PC will complain about not finding the files, but will soon get over it,
67allowing you to enter the new password.
68</p><p>
69If you do not do this, you may find that Windows for Workgroups remembers and uses the old
70password, even if you told it a new one.
71</p><p>
72Often Windows for Workgroups will totally ignore a password you give it in a dialog box.

75There is a program call <code class="filename">admincfg.exe</code> on the last disk (disk 8) of the WFW 3.11 disk set.
76To install it, type <strong class="userinput"><code>EXPAND A:\ADMINCFG.EX_ C:\WINDOWS\ADMINCFG.EXE</code></strong>. Then add an icon
77for it via the <span class="application">Program Manager</span> <span class="guimenu">New</span> menu. This program allows
78you to control how WFW handles passwords, Disable Password Caching and so on, for use with <a class="link" href="smb.conf.5.html#SECURITY" target="_top">security = user</a>.

80UNIX passwords can be case-sensitive though. Check the <code class="filename">smb.conf</code> information on

82Samba should try to uppercase when checking.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2690230"></a>Use TCP/IP as Default Protocol</h3></div></div></div><p>To support print queue reporting, you may find
83that you have to use TCP/IP as the default protocol under
84Windows for Workgroups. For some reason, if you leave NetBEUI as the default,
85it may break the print queue reporting on some systems.
86It is presumably a Windows for Workgroups bug.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="speedimpr"></a>Speed Improvement</h3></div></div></div><p>
87Note that some people have found that setting <em class="parameter"><code>DefaultRcvWindow</code></em> in
88the <em class="parameter"><code>[MSTCP]</code></em> section of the
89<code class="filename">SYSTEM.INI</code> file under Windows for Workgroups to 3072 gives a
90big improvement.
91</p><p>
92My own experience with DefaultRcvWindow is that I get a much better
93performance with a large value (16384 or larger). Other people have
94reported that anything over 3072 slows things down enormously. One
95person even reported a speed drop of a factor of 30 when he went from
963072 to 8192.

98When using Windows 95 OEM SR2, the following updates are recommended where Samba
99is being used. Please note that the changes documented in
100<a class="link" href="Other-Clients.html#speedimpr" title="Speed Improvement">Speed Improvement</a> will affect you once these
101updates have been installed.
102</p><p>
103There are more updates than the ones mentioned here. Refer to the
104Microsoft Web site for all currently available updates to your specific version
105of Windows 95.

107Also, if using <span class="application">MS Outlook,</span> it is desirable to
108install the <code class="literal">OLEUPD.EXE</code> fix. This
109fix may stop your machine from hanging for an extended period when exiting
110Outlook, and you may notice a significant speedup when accessing network
111neighborhood services.

113Configure the Windows 95 TCP/IP registry settings to give better
114performance. I use a program called <code class="literal">MTUSPEED.exe</code> that I got off the

117There are several annoyances with Windows 2000 SP2, one of which
118only appears when using a Samba server to host user profiles
119to Windows 2000 SP2 clients in a Windows domain. This assumes
120that Samba is a member of the domain, but the problem will
121most likely occur if it is not.
122</p><p>
123In order to serve profiles successfully to Windows 2000 SP2
124clients (when not operating as a PDC), Samba must have
125<a class="link" href="smb.conf.5.html#NTACLSUPPORT" target="_top">nt acl support = no</a>
126added to the file share that houses the roaming profiles.
127If this is not done, then the Windows 2000 SP2 client will
128complain about not being able to access the profile (Access
129Denied) and create multiple copies of it on disk (DOMAIN.user.001,
130DOMAIN.user.002, and so on). See the <code class="filename">smb.conf</code> man page
131for more details on this option. Also note that the
132<a class="link" href="smb.conf.5.html#NTACLSUPPORT" target="_top">nt acl support</a> parameter was formally a global parameter in
133releases prior to Samba 2.2.2.
134</p><p>
135<a class="link" href="Other-Clients.html#minimalprofile" title="Example 44.1. Minimal Profile Share">Following example</a> provides a minimal profile share.

137The reason for this bug is that the Windows 200x SP2 client copies
138the security descriptor for the profile that contains
139the Samba server's SID, and not the domain SID. The client
140compares the SID for SAMBA\user and realizes it is
141different from the one assigned to DOMAIN\user; hence,
142<span class="errorname">access denied</span> message.
143</p><p>
144When the <a class="link" href="smb.conf.5.html#NTACLSUPPORT" target="_top">nt acl support</a> parameter is disabled, Samba will send
145the Windows 200x client a response to the QuerySecurityDescriptor trans2 call, which causes the client
146to set a default ACL for the profile. This default ACL includes:
