Windbg 3.0.0010.0,ntoskrnlsym.dbg/.pdb files r missing

I am using windbg 3.0.0010.0 for kernel mode driver.
i have copied all the symbols directory from WinNT
4.0(checked build)and sp 5 cd’s to host m/c and set
this directory as symbol path in windbg.when i set
breakpoint in the source code then a message comes
“Symbol information for current line could not be
located in the current loaded symbols”, i click “Yes”
option in this message which perform the search for
symbols.then it displayed “could not found, breakpoint
not set”.when i run “.reload” command,now i am able to
set breakpoint in source code which comes in “Red”
color.but when i set any variable in “watch” window it
is not showing the current value of variable and a
error have comes in command window
******************************************************
Your debugger is not using the correct Symbols In
order for this command to work properly, your symbol
path must point to .pdb files that have full type
information.
Certain .pdb files (such as the public OS symbols) do
not contain the required information. Contact the
group that provided you with these symbols if you need
this command to work

**************************************************

then i on the noisy mode and run “.reload /fi”,it is
showing
DBGHELP: diaLocatePDB-> Looking for ntoskrnlsym.pdb…
file not found
DBGHELP: FindDebugInfoFileEx-> Looking for
ntoskrnlsym.dbg… file not found

i have searched this files in WinNT 4.0(checked
build)and sp 5 cd’s but they do not contain
"ntoskrnlsym.dbg " and “ntoskrnlsym.pdb” files.

pls suggest me solution.

Regards
Akhil
