Error: c0000135 and RPCRT4.DLL Problem

[Guest]

Here is the story:

Yesterday, windows told me (a message in the lower-left corner) that my
rpcrt4.dll file is corrupted and it's suggested to run chkdsk. First I wanted
to run defragmentation, but it told me that chkdsk is schleuded, so i've
restarted my laptop, and chkdsk REMOVED my corrupted rpcrt4.dll . So
everytime i've started windows, the blue screen appeared with the text:
"Error - c0000135 The application failed to start up because rpcrt4.dll was
not found".
By using Windows XP Installation disc and it's repair feature, i've copied
the file from the CD. From now on my Windows starts almost normally, except:
-it's taking long,
-a lot of the previously installed programs don't work, for example Windows
Defender crashes up on startup, Defragmentation says it cannot connect to the
defragmentation utility, sound drivers don't work, windows installer also,
and so on.

Okay, so my question is, do any of You know what's in that file? Can I
repair it somehow without backupping my HD and reinstalling? Does my Windows
only lacks registry entries, and if so can is there a way to restore them
manually?

Here is the story:

Yesterday, Windows told me (a message in the lower-left corner) that my
rpcrt4.dll file is corrupted and it's suggested to run chkdsk. First I wanted
to run defragmentation, but it told me that chkdsk is scheduled, so i've
restarted my laptop, and chkdsk REMOVED my corrupted rpcrt4.dll . So
everytime i've started windows, the blue screen appeared with the text:
"Error - c0000135 The application failed to start up because rpcrt4.dll was

defragmentation utility, sound drivers don't work, windows installer also,
and so on.

Defragmentation shifts fragmented sections around to improve access
speed; it won't help with damaged and missing files.

Your HD might be failing you if so many files are missing and damaged.
For system files, you can run SFC and have them repaired. (See below.)
But, if the HD is failing, you need to get a new one before important
data is lost. There's also the possibility that some malware has
deleted/damaged files, I suppose.

Click Start, Run, type SFC /SCANNOW, click OK. If any are damaged or
missing files, they'll be replaced. You may need to reboot afterwards
so damaged files will be replaced.
