I copied an XP partition with DD10 and the default FIREWALL was unreachable, obviously corrupted. DD10 was a near infallible partition copying machine until about a month ago (perhaps it's time to uninstall/reinstall DD10: I have really punished DD10 having it do dozens of operations including ones I knew stretched it's capabilities). Checked out the rest of the copy and the firewall problem seems to be the extent of the corruption. The "User Accounts" or "Internet Explorer" sections were not corrupted in this copy as previous DD10 copies exhibited. Since SP2 includes the default firewall I decided to reinstall SP2 "on top" of the SP2 that the XP had already had. (I was going to re-do the operation anyway so no problem if the partition was trashed: a little exciting experimentation is good for old hearts). Copying this "Makeshift slipstreamed XP" was 3 min. faster than using TI10. This over-installation of SP2 went well and has been working well for over three weeks. Download from the Microsoft site and SAVE SP2 as a FILE and make a cd of it; very handy to have in any XP toolkit. In Windows Explorer there was no duplicate SP2 files, so I believe it replaced the original SP2 with the Disc version (which is identical as far as I know). The default firewall was restored and all functions returned. I Don't know if this will work on all other systems, but I believe it can on many. This could be a solution to those systems that always result in a corrupted Firewall when "Copying Partitions". This allows one to turn off the firewall if another is used. For "Copy Partition" operations with "User Accounts" and "Internet Explorer" corruption, downloading "Internet Explorer 7" had cured these corruptions as I posted before . Perhaps this can help some, especially those who do not have TI10 (or can't get it to work correctly).
