well, this one is new to me. I had a virus actually delete my SVCHOST.EXE. Then as per it should, my computer did the "must close in 60 seconds" routine cause its missing blah blah.

So It restarted and its back up but i cant open any program, use the net, or anything like moving a new SVCHOST.EXE back in (had a backup form one of my other programs). So I cant fix it.

Is there any way? I tried going into safe mode but that didnt een work. I cant think of anything short of a XP CD repair or reformat. But for 1 file? Therse gotta be a way.

If you cannot use run, press ctrl + alt + delete keys together to get task manager, click file then new task, type sfc /scannow then press enter

Click start then run, type sfc /scannow then press enter to replace the system files, you need the XP CD.

Windows File Protection will show an on screen blue progress bar, reboot when the bar goes

System File Checker gives an administrator the ability to scan all protected files to verify their versions. If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version of the file from the cache folder %Systemroot%\System32\Dllcache or the Windows installation source files, and then replaces the incorrect file.

System File Checker also checks and repopulates the cache folder. You must be logged on as an administrator or as a member of the Administrators group to run System File Checker.

The System File Check is only concerned with replacing missing or corrupt system files, and does not affect installed software or data

Start the System Restore tool at a command prompt

1. Restart your computer, and keep tapping F8 during the initial start-up until you get options, select Safe Mode with a command prompt then press enter.

2. Log on to your computer with an administrator account or with an account that has administrator credentials.

3. Type the following command at a command prompt, and then press ENTER:


%systemroot%\system32\restore\rstrui.exe

4. Follow the instructions that appear on the screen to restore your computer to an earlier state.

Look for the most recent system checkpoint created before the errors to restore from

For additional information about the Safe mode with a command prompt, click the following article number to view the article in the Microsoft Knowledge Base:

That is unknown to me. I haven't used it in ages. I would say when this happend, but I cant because of that reason. So it could have been a long time ago just because of a loose connection or something. I don't have an answer for that.

If you know exactly which file is missing, you could use another PC to explore the XP CD, copy the file and e-mail it to this PC then put it back in the correct folder

The other consideration is, if sfc ran and did not ask for the disc then it isn't a missing system file, also there are usually a number of instances of svchost.exe running

Do you have trouble connecting to the internet

I get this error when I load windows and log-in:

System Error %H800706BA(-2147023174). The RPC server is unavailiable.

Just noticed that now.

I cannot connect to the internet, I do not have a start menu or bottom bar.
I cannot move items, copy, or paste items.

The only thing deleted was SVCHOST Im pretty sure

If you press ctrl + alt + delete keys together, do you get task manager, if so, click file then new task, type explorer.exe then press enter, if you get the start menu, click start then run, type services.msc, (or do the same with task manager, file new task) then press enter, check the RPC is started

If you cannot get those then you should look at a repair install but you need to see what the problem is with the CD Rom

You can use this guide to repair XP

Possibly, you will need to boot the PC and keep tapping the delete key until the PC enters set up. Change the boot order to CD ROM Drive then hard drive, press F10 then press enter, type Y then press enter and as it reboots, look for press any key to load from CD, press enter

XP Repair Install

Windows XP repair feature won't delete your data, installed programs, personal information, or settings. It just repairs the operating system

After running XP Repair you will need to install all Windows Updates

Microsoft Update

Ok I got services up found Remote Procedure Call (RPC) its set to Automatic Startup type, and RPC Locator set to manual.

I right clicked RPC and clicked STart and got this error:

Could not start the RPC service on Local Computer.
Error 2: The system cannot find the specified file.


So I tried to locator and got this:

Could not....
Error 1068: The dependency service or group failed to start.


So Its missing what ever file that is.


Edit:

YEs it only has the one CD Drive.

Whichever way you got run to work, type devmgmt.msc to get device manager, then locate the CD ROM Drive, right click it, click remove, confirm then reboot, windows will re-install it as it loads

If it still does not work, switch all the power off, if the PC tower has an off switch by the power lead, use that, and also remove the power lead, open the case to see if you cn spot anything obvious which is causing the drive to not work

If you do not see anything you can remove the drive and see if a local repair shop will check it for you
