Background

Windows 7 was released in October 2009. Due to changes in the way that trust relationships are established with domain controllers, some modifications to the windows registry needs to take place.

Join a Window 7 client to SME Server 8 or 9

Previously you needed to edit your Win7 registry to facilitate the joining of a SME Server Domain, however this can more easily be achieved by importing win7samba.reg fix by using either a usb key or by the network with http.

Save the Win7 registry patch (win7samba.reg) from https://your-server-ip/server-resources/regedit/ with your favourite web browser
On your windows desktop, start "regedit" from the start menu and import the win7samba.reg
Set your domain instead of your workgroup. Add the client machine to the domain as normal.
When asked on your Windows PC use the 'admin' username and your SME Server admins password.
You have to reboot your computer to reach the domain

	Tip:
	To connect a windows Seven client to your domain, Go to the "start menu", right click on computer, select "Properties", select the link "change Settings", then click on "Change" Tab.. Enter your servers "Domain" value in the domain field and 'Connect'. Enter the username of admin(*) with the servers admin password when asked, and you should get back the response 'Connected to Domain'.

(*) Admin or any user in the 'Domain Admins' group can join the domain.

Note:

You will receive one warning about DNS domain name configuration after the join has succeeded:

  "Changing the Primary Domain DNS name of this computer to "" failed.
   The name will remain "MYDOM".  The error was:
   
   The specified domain either does not exist or could not be contacted"

But this error can safely be ignored or, if you run Windows 7, silenced by a hotfix, that was published by Microsoft: KB2171571: You incorrectly receive an error message when you join a computer that is running Windows 7 or Windows Server 2008 R2 to a Samba 3-based domain.

Setting up network drives

If you are using SME Server as a domain controller and the workstations have joined the domain you can automate drive mapping and syncronise the PC time with the netlogon.bat file

Note: Chapter 13 has a method for admin to edit the netlogon.bat file without using the command line. You can consider also the chapter 7 on Configuring the Computers on Your Network

nano -w /home/e-smith/files/samba/netlogon/netlogon.bat

REM To set the time when clients logon to the domain:
net time \\servername /set /yes
REM To map a home directory to drive h:
net use h: /home /persistent:no
net use j: \\servername\ibay1 /persistent:no
net use p: \\servername\ibay2 /persistent:no
if exist Z: net use Z: /del /yes

and reset file to dos format

unix2dos /home/e-smith/files/samba/netlogon/netlogon.bat

Slow login with win7 to sme8 domain

With certain networks you may have an issue with a slow login to the SME Server domain due to a timeout issue on the network. In this case you should install a second patch (in first you have to install the win7samba.reg). The history of this patch can be found at ~~bugzilla:7332~~ The version of package needed e-smith-samba-2.2.0-57.el5.sme is in smeupdates-testing but will shortly be by default in smeupdates so in the first instance verify your package version

rpm -qa e-smith-samba
e-smith-samba-2.2.0-57.el5.sme

You need at least this version as above, otherwise try this

yum update --enablerepo=smeupdates-testing e-smith-samba
signal-event post-upgrade; signal-event reboot

This is what you need to find in your server-ressources

cat /home/e-smith/files/server-resources/regedit/windows_samba_performance.reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System]
"SlowLinkDetectEnabled"=dword:00000000
"DeleteRoamingCache"=dword:00000001
"WaitForNetwork"=dword:00000000
"CompatibleRUPSecurity"=dword:00000001

After this you follow the usual way to add the patch to your windows registery

Save the registry patch (windows_samba_performance.reg) from https://your-server-ip/server-resources/regedit/ with your favourite web browser
On your windows desktop, start "regedit" from the start menu and import the windows_samba_performance.reg

Adding Windows 7 Support to SME Server 7

Configuring Clients

Install the Windows 7 registry patch from http://yourserver/server-resources/
Add the client machine to the domain as normal.

	Note:
	You may see an error message on join regarding primary DNS suffix. This doesn't seem to affect any actual functionality

	Note:
	You may see an error message when logging in for the first time. This appears to be a once off timeout issue which does not recur.

Refer to ~~bugzilla:5897~~ and ~~bugzilla:7002~~ for details of following error

	Note:
	You may see an error message "The specified domain either does not exist or could not be contacted." when logging in for the first time. This is a harmless message. Windows 7 after it joins the domain tries to resolve its dns name (and assumes that the domain controller will setup a dns entry for its hostname. See following for a MS hotfix [1]

Roaming Profiles

Windows 7 clients require that a version 2 profile folder exist in the profiles$ share, which on SME Server is located in /home/e-smith/files/samba/profiles.

This additional profile folder is automatically provisioned for existing users when the installing latest version of e-smith-samba (see ~~bug 5423~~). After this point, all new user accounts have the folder created as soon as they are added.

	Note:
	If version 2 profile folders are not available, Windows 7 will create a temporary profile when you log in. Should you experience this problem, make sure that your SME Server installation is fully up to date.

Version 2 profiles are not compatible with Windows XP and earlier. If you have mixed environments you will be required to maintain two separate profiles for each user.

Source Code

SerNet publishes the source code for their latest Samba build at http://ftp.sernet.de/pub/samba/3.5/src/rpm/

Code for older builds is also available at http://ftp.sernet.de/pub/samba/old/src/rpm/
