Okay, here's the situation. I'm rolling out XP. I want to use RIS for speed and so everyone gets the same build. I want the XP that gets installed to have as many of the programs we'll be using as possible, but for right now I'm stuck just on the Microsoft stuff. I ran RISETUP on my server and had it copy over the install files from my Windows XP CD-ROM. The CD has service pack 1 applied already. (It's a gold volulme license key CD from Microsoft, not something I slipstreamed myself.) I boot a computer using the RBFG.exe boot disk. The machine finds the RIS server and XP gets installed. I go to the newly created machine and run Windows Update to get the latest hotfixes, .NET framework, stuff like that. At this point, I've got XP SP1 with all the latest updates and Microsoft software (DX9, .NET framework, etc.) Before going any further I want to put an image of that system back up on my RIS server. But I can't. I run riprep from the RemInst share on my RIS server, and I get the error message "The RIS server to which you are attempting to post this installation does not have the correct CD-based image..." This error is discussed in MS KB article 324573 -- http://support.microsoft.com/default.aspx?...kb;en-us;324573 Some hotfix I installed modifies ntoskrnl.exe. The version on my RIS server is 5.1.2600.1106 and the version on my new XP box is 5.1.2600.1151. Because of the mismatch RIS won't accept the OS image. (I'm not sure which hotfix modifies ntoskrnl.exe, maybe it would be easiest to just not apply that one and run it in a script after the OS is installed...) My plan was to create an install of XP that's got all the latest hotfixes applied. This looks to be extremely time consuming. I'm thinking now that the easiest thing will be a batch file to run Qchain and all the hotfixes I want. As new hotfixes come out, I'll just need to modify by batch file and make sure the hotfix executable gets into the right folder. It's very annoying that I can slipstream a service pack, but can't (easily) slipstream a hotfix. The Microsoft suggestion described in http://www.microsoft.com/WindowsXP/pro/dow...p1/hfdeploy.asp involves expanding the Qxxxxxx.exe hotfixes, finding the latest binaries, and replacing the compressed binaries in my RIS i386 folder with the ones from the expanded hotfixes. Then you have to make a list of all the .cat files as well. For twenty-two hotfixes, that's WAAAAY too much work. I'm getting paid by the hour but I need to get this job done too Thanks for taking the time to read all this! And thanks for fixing your link GreenMachine. Mabye my answer is there.
