Downloading And Installing Updates - Lenovo ThinkServer TD100 Deployment Manual

Downloading and installing updates

The following list provides the three different methods you can use to download
and install update packages:
v Lenovo Help Center Web site
v Locally on a client system
v Network shared drive
The following sections define each method in detail, so that you can provide the
best configuration for your organization.
Using the Lenovo Help Center Web site
You can manually initiate a check for new updates using EasyUpdate. EasyUpdate
notifies you that the following information is communicated to determine the
applicable update packages for your system:
v Machine type
v Operating system
v Language
EasyUpdate will then provide a selectable list of updates. You will have the option
to defer updates, so you can download the update package but install it at a later
time, or you can download and install the update packages immediately. Once you
select the updates to download and confirm the selections, the updates are
downloaded and installed your system.
Using a repository on a client system
You can set up your computer to store update packages locally. Do this by creating
a folder on your computer to be used as the repository, and then change the
repository path in the registry that points to that repository on your local
computer.
Using a repository on a network share
You can download and install new updates from a repository that resides on a
network share. EasyUpdate will retrieve the end user credentials (user name and
password) needed for authentication from the application properties as encrypted
strings. If a user name and password does not exist, EasyUpdate will still attempt
to connect to the network share but will prompt the user to provide a user name
and password.
Note: The user name and password properties can be managed by Active
Directory. Since the user name and password must be encrypted when used as an
application property, an administrator can use a Lenovo supplied utility called
MapDrv to generate encrypted strings for the user name and password using a
software key. For additional information about the MapDrv utility, see "Map Drive
utility" on page 72.
The following keys are used to store the user name and password:
HKLM\Software\Lenovo\MND\TSEUAPPLICATION\UNC=<network share>
HKLM\Software\Policies\Lenovo\MND\TSEUAPPLICATION\UNC=
<network share>
HKLM\Software\Lenovo\MND\TSEUAPPLICATION\Pwd=
<encrypted password>
If an Active Directory policy is used, these values are stored at:
HKLM\Software\Policies\Lenovo\MND\TSEUAPPLICATION\UNC=
<network share>
