3.
Patch and recovery phase
When the machine reboots in Windows XP, Antidote Delivery Manager begins
processing again even before the user can log in. Patches should be installed at
this time. The machine can be rebooted if the newly installed patches require it.
Now that all cleanup and patching has been completed, the network can be
enabled and the user is informed that normal operation is possible.
Minor application update
Not all maintenance requires the drastic measures previously described. If a patch
is available, but a virus attack is not in progress, a more relaxed approach might be
appropriate.
A single script can control the operation through the use of the RETRYONERROR
command and tag files.
1.
Download Phase
The process begins with a message box informing the user that a patch will be
downloaded for later installation. Then, the patch can be copied from the
server.
2.
Patch phase
The patch code is ready for installation and it is time to warn the user to start
installation. If the user requests a delay, a tag file could be used to track the
delay. Perhaps later requests to install the patch might be more urgent.
Antidote Delivery Manager maintains this state even if the user powers off or
reboots their system. When the user has completed all processing and is ready
for a system reboot, the patch is installed and the system is rebooted, if
required.
Attention:
After a system has been restored and rebooted, reboot the system
again in order for changes to take effect.
Accommodating VPNs and wireless security
The Rescue and Recovery environment does not currently support either remote
access Virtual Private Networks (VPN) or wireless network attachments. If a
machine is using one of these network attachments in Windows XP, and then
reboots to Rescue and Recovery, network connectivity is lost. Therefore, a script
like the one in the previous example does not work because networking is not
available in Rescue and Recovery to download files and fixes.
The solution is to package all required files in the original message or download
the needed files before rebooting. Place all necessary files in the directory with
go.rrs. The script file must move the required files into their final positions before
exiting the script (when the directory containing go.rrs on the client is deleted).
Placing patches in the message file might not be practical if the patches are very
large. In this case, the user should be informed, then networking is restricted to
only the server containing the patch. Then the patch can then be downloaded
while still in Windows XP. Although this can lengthen the exposure of Windows
XP to a virus, the extra time is probably not significant.
