For W2K, Parseus offers an extension: HFSLIPFC-2K. Put this file also in the HFSLIP-folder, fill the SOURCES-folder with W2K and start the file-checker. If you have an older INI, rename your current hfslipfc.ini and let hfslipfc create a new INI. There are some other options for W2K Fine... today i will give a try. I had slipstreamed all your updates (except SP3) on my Windows Professional SP3 CD (MSDN ISO) the slipstream went fine, the instalation fine, all ok... then i got online to check for updates... it still shows KB905474! (Windows Genuine Notifications) I read on the now dead Hfslip homepage about this... which update must I have? should I inspect Windows Update.log (On Windows Folder) and see where Windows Update goes fetch the update? Or the update always proceeds this way (Will Always going to list as a missing update)? Besides that point... It's fully working All well slipstreamed! I Will Proceed to Slipstream a Windows 2000 CD Thanks a Lot mim0 If i could help you guys... shout!
