It is a worm that causes this problem

What You Should Know About the Blaster Worm and Its Variants
http://www.microsoft.com/security/incident/blast.asp

first do this

Start > Run services
Double Click on Remote Procedure Call (RPC)
Click the Recovery tab
Set all three failure boxes to "Take No Action"

Then open the task manager Start > Run taskmgr and under the Processes tab look for msblaster.exe and if you find it end the task.

then

Removal tool

Download
http://securityresponse.symantec.com/avcenter/FixBlast.exe

http://securityresponse.symantec.com/avcenter/venc/data/w32.blaster.worm.html

W32.Blaster.Worm is a worm that will exploit the DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026) http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/bulletin/MS03-026.asp using TCP port 135. It will attempt to download and run the file Msblast.exe.

You should block access to TCP port 4444 at the firewall level, and block the following ports, if they do not use the applicaitons listed:

TCP Port 135, "DCOM RPC"
UDP Port 69, "TFTP"

The worm also attempts to perform a Denial of Service on windowsupdate.com. This is an attempt to disable your ability to patch you computer against the DCOM RPC vulnerability.

Click here http://securityresponse.symantec.com/avcenter/security/Content/8205.html for more information on the vulnerability being exploited by this worm and to find out which Symantec products can help mitigate risk from this vulnerability

Restarting the computer in Safe mode or ending the Worm process
Restart the computer in Safe mode. All the Windows 32-bit operating systems, except for Windows NT, can be restarted in Safe mode. For instructions on how to do this, read the document, "How to start the computer in Safe Mode."

Windows NT/2000/XP
To end the Trojan process:
Press Ctrl+Alt+Delete once.
Click Task Manager.
Click the Processes tab.
Double-click the Image Name column header to alphabetically sort the processes.
Scroll through the list and look for msblast.exe.
If you find the file, click it, and then click End Process.
Exit the Task Manager.

5. Reversing the changes made to the registry

CAUTION: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. Read the document, "How to make a backup of the Windows registry, http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/199762382617 " for instructions.

Click Start, and then click Run. (The Run dialog box appears.)
Type regedit

Then click OK. (The Registry Editor opens.)

Navigate to the key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

In the right pane, delete the value:

"windows auto update"="msblast.exe"

Exit the Registry Editor.


Now apply the patch
