I was not using the MSOOBE patch, because I didn't want OOB to run, but I put the patch in there now. Also, I did find the IE patch in my source's svcpack folder, and removed it (cleared out the whole folder). The source I was using was the latest XP downloadable image from MS Volume Licensing. I'm slipstreaming a new image now, and will try installing on MS Virtual PC once it's done, and let you know if that did the trick.
