Hello,
Here is some additional information along with additional links.
Stop Windows XP and Windows Server 2003 systems from rebooting after an
attack:
Another way to prevent Windows XP and Windows 2003 Server systems from
rebooting once the count down has started is to run this command at
the command line:
shutdown /a
This aborts the shutdown sequence. Since the RPC service has already
been shut down, it cannot be shut down again. Then you can patch the
system with MS03-026 which will reboot the system once it’s installed.
This command is not available on pre-XP systems.
Change Service Properties to avoid the reboot:
1. Open up the Services snap-in.
This can be done by right clicking on"My Computer", select"Manage",
select"Services and Applications" and click on"Services".
This can be done by going to the Control Panel and selecting to
switch to"Classic View", double-click on"Administrative Tools" and
select"Services".
2.Double-click on the"Remote Procedure Call (RPC)" service.
3. On the User Interface for RPC, click the"Recovery" tab.
4. Under the"Recovery" tab, go to the"First failure:" drop down and
change the value from"Restart the Computer" to"Restart the
Service".
5. Change the"Restart service after:" value to 5 minutes.
6. Install the MS03-026 / 823980 on the computer.
