This is going to be a little long winded so I apologize in advance. Gotta problem with a Shuttle barebones system I put together about 1.5 years ago. 80G hd, 500mg ram, P4 2.4ghz CPU, Benq DVDRW, Windows XP MCE. Client brought it back when windows was unable to completely boot. I thought it probably had a virus, but could do nothing to get it booted to desktop so I could run antivirus software. I ended up reformatting and reloading Windows XP MCE. 1. During install, system was looking for SP2 disc. How could it know I had it. I don't believe I had SP2 when I first installed MCE a year and a half ago. When I inserted disk it couldn't find several files. I continued with install anyway. 2. After installation of Windows I attempted to load MB drivers from disk supplied by manufacturer. This is when I got the error message. "Install Shield engine ikernel.exe could not be launched RPC server is unavailable". So I tried to log on to Internet with a working connection, but system wasn't seeing my DSL modem. When I tried to make a connection I got a memory error. I also notice that Internet Explorer was not installed. So I thought maybe a bad hard drive. 3. I installed a new hard drive, reloaded windows....system was again looking for sp2 disc, and again couldn't see a couple of files. When I got system booted up I loaded SP2 from disk. Tried to load MB drivers from disc and got same ikernel error as above. Seems like windows only half loaded. There seems to be several missing components including IE. I tried downloading drivers from Shuttle website, updating bios, load optimized defaults. Nothing works I am able to load antivirus and Firefox from disk. Antivirus runs but finds nothing (no surprise), This system still doesn't see dsl connection and can't launch firefox. Any thought to this ikernel.exe error?
