Slipstreaming SP3 into MCE2005 has caused problems. Can it be done? Well here is one solution I worked on, and at least it worked for me.
1. Backup the files medctroc.dl_, medctroc.in_, mediactr.ca_ from i386 to another folder.
2. Slipstream SP3 (sp3.exe /integrate:<path>).
3. Replace the files medctroc.dl_, medctroc.in_, mediactr.in_ with ones you backed up earlier.
4. Expand the file wbemoc.in_ to wbemoc.inf (To do this open a command prompt and type expand /r wbemoc.in_)
Open the file and find the section [WBEM.CopyMOFs]
Find napclientprov.mof and change to napclientprov.mof,napprov.mof
Find napclientschema.mof and change to napclientschema.mof,napschem.mof
Save the file, compress it (type makecab wbemoc.inf in the command prompt) then delete wbemoc.inf.
5. Expand the sysoc.in to sysoc.inf
Open the file, and in the section [Components] add the following:
SonicDVDandCDBurning=ehOCGen.dll,OcEntry,sonic.inf,,7
WinPlus=plusoc.dll,OcEntry,plusoc.inf,,7
Save the file, compress it (makecab sysoc.inf) then delete sysoc.inf.
6. Open txtsetup.sif
Find the lines
medctroc.dll = 100,,,,,,,32,0,0
medctroc.inf = 100,,,,,,,20,0,0
mediactr.cat = 100,,,,,,,,3,3
Then insert the following:
ehOCGen.dll = 100,,,,,,,32,0,0
sonic.inf = 100,,,,,,,20,0,0
sonic.cat = 100,,,,,,,,3,3
sonic.cab = 3,,,,,,_x,,3,3
plusoc.dll = 100,,,,,,,32,0,0
plusoc.inf = 100,,,,,,,20,0,0
plus.cat = 100,,,,,,,,3,3
plus.cab = 3,,,,,,_x,,3,3
Save the file.
7. Extract the SP3 Package to a folder using sp3.exe /x:<folder>
In the folder i386\root\cmpnents\netfx\i386 you will find a updated NETFX.CAB which is not slipstreamed. Copy the file and replace the existing one in your cmpnents\netfx\i386 folder with the new one.
8. Finally burn to a DVD
Step 1 and 3 will make sure the 2005 version of Media Center is installed.
Step 4 will solve the napclientprov file missing problems.
Step 5 and 6 will install the Digital Media Enhancements and Sonic Burning as usual.
Step 7 Updates Netfx 1.0
Issues:
WMP9 is installed and not WMP10. Not a problem if you're planning to install WMP11.
