after 2 years of successful unattended cds, suddenly I've got on both my pcs these fatal errors at setup. I haven't found a reason. I made no modifications to their structure, always working in the past: deleting unuseful directories (support, sbsi, docs, valueadd, lang, win9xupg, ecc.) create my own Winnt.sif file and $OEM$ directory, containing cmdlines.txt and runonceex.cmd file for installing a few applications. I say, it always worked but now during setup, at T-15 (registering components) appears the following error message, who says (sorry, I translate from Italian: don't know if it's the exact phrase): "unable to load internet connection wizard - unable to find Icfg95.dll" Sure! That file doesn't exist on xp cd... now why do you ask for it? If i click on OK, the setup goes on normally. But at the last restart, when Runonceex.cmd is execute, new messages appear: "the windows installer service could not be accessed. You may be running in safe mode or windows installer may not be correctly installed" when Runonceex.cmd runs a .msi file. And again: "RPC server is unavailable..." when XP tries to install the printer driver, I've made hundreds of attempts, but it's always the same: my unattended cd, always perfect till yesterday, now works only with SP2 slipstreamed and Winnt.Sif. If I modify everything more...error! The problem appears before cmdlines.txt processing, so I don't think it's a $oem$ problem, and it is the same on 2 different pc. I googled for it but never read of something similar... Systems are both Win XP SP2 Home Italian OEM. Attached is the template of my Winnt.sif file (i also tried to remove some strings but with no success) Tnx WINNT.SIF
