Any help would be greatly appreciated as I have 3 of these which are domain controllers running certificate services.<BR /><BR />Many thanks in advance :-) Thu, 22 Apr 2010 14:12:53 GMT https://community.hpe.com/t5/operating-system-microsoft/in-place-upgrade-dl380-g4-win2003-2008/m-p/4622434#M12129 Steve Violaris 2010-04-22T14:12:53Z https://community.hpe.com/t5/operating-system-microsoft/in-place-upgrade-dl380-g4-win2003-2008/m-p/4622435#M12130 I had the same problem. <BR />Resolved it by deleting driver lsicsb6.sys from %systemroot%\system32\drivers (needed to boot from win2008 install cd for this) Tue, 25 May 2010 23:54:26 GMT https://community.hpe.com/t5/operating-system-microsoft/in-place-upgrade-dl380-g4-win2003-2008/m-p/4622435#M12130 Sergey Chmel 2010-05-25T23:54:26Z
