terminal services is not available in "services" and remote desktop is not available in "my computer" properties dialogue box. Win XP SP3. Result - unable to install Serch 4.0.
@Hawkeye, I have WinXp Home and if you type 'mstsc' (microsoft terminal services (console?)) it will bring up a box named Remote Desktop.
@funkeyro, I had the same issue with a copy of WinXp Pro that came with a replacement computer we had gotten from a person. It looked like some sp2 updates failed which apparently left out 'terminal services' from services.msc and still did not add with a clean sp3 install (although with a not so clean sp2 update I guess sp3 not quite so clean) and as a result cannot add a/v, let a company take control of computer for help, etc. And had same issue with adding terminal services by not being able to find it anywhere on the M$ website since it should already be installed with sp updates.
Hopefully this will help someone else in the future plus the great posts prior to this one.
