Dear Customer,
Thank you for contact Microsoft Online Support Service. My name is Pavan
Pediredla and I will be working with you on this service request.
As I understand, you have received the following error messages when using
your computer:
"This system is shutting down. Please save all work in progress and log off.
This shutdown was initiated by NT Authority/System."
"Windows must restart because the Remote Procedure Call (RPC) service
terminated unexpectedly."
If I have misunderstood, please feel free to let me know.
This is a known security issue which was first found on July 15. There is
currently an Internet Worm that is taking advantage of this security issue.
Microsoft published the patch to fix this issue on July 16 for all of the
affected systems on our web site. For more information, please refer to the
following page:
http://www.microsoft.com/security/security_bulletins/ms03-026.asp
The resolution to this issue is to clean the worm from your system and
install the patch mentioned above. You can find a link below to install the
patch for Windows XP.
It is suggested that you first download the patch to your system so you can
install the patch immediately after cleaning the system and before you
reconnect to the Internet or network.
In some cases this Worm can cause your system to reboot and you may have
difficulties downloading the patch. In those cases you need to turn off
some ports that the virus uses by blocking them with Firewall software. The
ports that may need to be blocked are as follows:
TCP/UDP Port 135
TCP/UDP Port 139
TCP/UDP Port 445
*Note: Port 69 (TFTP) and TCP port 4444 are also in use by this worm and
should be blocked.
The Internet Connection Firewall that comes with Windows XP will block these
by default once it is enabled. To enable the Internet Connection Firewall
that comes with XP do the following:
1. In Control Panel, double-click "Networking and Internet Connections",
and then click Network Connections.
2. Right-click the connection (your internet connection) on which you would
like to enable ICF, and then click Properties.
3. On the Advanced tab, click the box to select the option to "Protect my
computer or network".
4. If you want to enable the use of some applications and services
through the firewall, you need to enable them by clicking the Settings
button, and then selecting the programs, protocols, and services to be
enabled for the ICF configuration.
