DLL error on boot

[Guest]

My computer during boot displays "The application or DLL
C:\windows\system32\NCObjAPI.DLL is not a valid windows image please check
check this against your installation diskette" then it boots very slowly. It
also operates very slow. Can anyone tell me what that DLL is and how to fix
it ? I'm running XP pro SP2.
Thanks

Use System File Check to replace corrupt system files. In the command prompt
type the following

Description of Windows XP and Windows Server 2003 System File Checker
(Sfc.exe)
http://support.microsoft.com/?kbid=310747

sfc /scannow

-----
If the error still occurs and you have installed Service Pack 2 and have the
"ServicePackFiles" in the following location:::

c:\windows\servicepackfiles

then type the following in the run dialog box:

cmd /k copy %systemroot%\servicepackfiles\i386\ncobjapi.dll
%systemroot%\system32

The above command is all one line.

----
If you do not have the "ServicePackFiles" folder then insert your Windows XP
CD into the cd drive and type the following in the command prompt.

expand cddriveletter:\i386\ncobjapi.dl_ %systemroot%\system32

The above command is all one line.

----
You could also use the dllcache folder to replace the file. Type the
following in the Run dialog box:

cmd /k copy %systemroot%\system32\dllcache\ncobjapi.dll
%systemroot%\system32

The above command is all one line.

I just got the same message. But I can't load windows to run these cmd line
actions.

Any ideas as how to be able to copy this file over in recovery console.
I tried to do a system repair, but even that doesntwork when it get to
copying the following files:

ncobjapi.dll
cryptdll.dll
dhcpsrvc.dll

and some other dll file. INstallation won't copy them to the installation
folders as if they were write protected.

In the attrib for these files I get -a------

Any ideas? I am stumped

thx in advance

Try typing in these commands in the recovery console,

copy c:\windows\system32\dllcache\ncobjapi.dll c:\windows\system32
copy c:\windows\system32\dllcache\cryptdll.dll c:\windows\system32

For the dhcpsrvc.dll, I do not think this is a valid windows file. But there
is a file called "dhcpcsvc.dll". If this is the file then you would type

copy c:\windows\system32\dllcache\dhcpcsvc.dll c:\windows\system32

If you get any errors then try these commands

copy c:\windows\servicepackfiles\i386\dllcache\ncobjapi.dll
c:\windows\system32
copy c:\windows\servicepackfiles\i386\dllcache\cryptdll.dll
c:\windows\system32
copy c:\windows\servicepackfiles\i386\dllcache\dhcpcsvc.dll
c:\windows\system32

Your last resort would be inserting your Windows XP CD and type

expand CDDriveLetter:\i386\ncobjapi.dl_ c:\windows\system32
expand CDDriveLetter:\i386\cryptdll.dl_ c:\windows\system32
expand CDDriveLetter:\i386\dhcpcsvc.dl_ c:\windows\system32
