I'm trying to modify the default location that 'server.msi' uses for installation. Server.msi is the Front End server installation component of OCS 2007, and the path it defaults to is 'C:\Program Files\Microsoft Office Communications Server 2007 R2\Server\'. I want to change this to 'D:\Program Files\Microsoft Office Communications Server 2007 R2\Server\' (just a drive letter change), because I'm preparing an automated OCS server deployment via Altiris.
I'm not a packager by any means, but I've tried using Orca and WinInstallLE and from my uneducated view, it seems that TARGETDIR is the value to change within the MSI, but I have tried using 'D:\' and also '[WIPROPDriveD]' (as this appears to be what WinInsallLE uses when I change a drive letter). Neither work though, and when I run them I get a '2704' error from the MSI.
I reckon this is probably a very straightforward question for someone with packaging experience, but unfortunately I'm an infrastructure person, so in all honesty, I don't have a clue what I'm doing, even after having googled it for a while, so any help would be appreciated.
