Hi again, guys. First of all. Thanks to tommyp and Muppet Hunter for the latest HFSLIP test version, and the updated WinXP Hotfix list. I've slipstreamed win xp sp3, and when i was checking if all updates were installed ok, i've obtained these two results: QFECHECK - XPTEST.txtHFNETCHK - WU2.TXT The source is a spanish clean XP SP3 with the i386 folder untouched. I'm using the Muppet Hunter's hotfix list. As you can see, QFECHECK returns all ok, but HFNETCHK indicates problems with the 972260 update. I'm posting also: The hfslip log: HFSLIP.txtThe list of new files added to the source: NEWBIN.TXT Can anybody tell me if i have a real problem with that update? How can i resolve it? Thank you people.
