>Anyone else download the "full" SP3 and when trying to extract the file "vs6sp3_3.exe" it extracts "vs6sp3_5.cab", rather than "vs6sp3_3.cab, then all the following files are also off the correct sequence? Then, of course, the install fails because one of the .cab files are missing.

No problem here, but you aren't the first person to report problems with either the extraction from the .EXE or from the resultant .CAB files. I'd try downloading the whole thing again, or ordering the SP on CD from Microsoft.
