Hi,\nI have difficulty in understanding duprepare and dushare. First of all is \nthis for hotfixes only or can this be applied to service packs as well? (I \nknow very well that slipstreaming service packs works fine but I just want \ntest this one)\nWell I tried from a windows 98 computer to install windows xp sp2 and I left \nsp3 updates in a folder named updates then I prepared the dynamic updates via \nwinnt32 /duprepare:c:\updates (a screen appeared and wentoff)\nafterwards I ran winnt32 /dushare:c:\updates and I thought that windows 98 \nwould be upgraded to windows xp sp3 but I got windows xp sp2. Will you please \nexpalin what was wrong? Thanks in advance.
