I am no m$win expert, but I think that runing 'dcomcfng' from a DOS
shell and clicking on 'Default Properties' and clearing 'Enable Dcom on this
Computer' window is enough. No regedits, no 'tiney little applications' required.

You still need to patch the PC or install *nix on it though....

I'm not a professional or anything, but the last few Windows systems I have installed for people I have applied the following small registry 'patch' to them before going online to download the countless amounts of updates:

--- begin nodcom.reg ---

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole]
"EnableDCOM"="N"

--- end nodcom.reg ---

I do agree that you still should patch it, but after the first time of going through an install only to be infected with the worm while downloading the updates was enough to drive a person mad.  This is a very simple workaround for something that IMHO isn't very severe any more.
