Unable to get the symbols file for wow64cpu.dll from 64-bit Windows 2003 Server SP2.
I'm having a dump of a 32-bit process that was executing on 64-bit Windows 2003 Server SP2.
I've discovered that every thread of the process ends up it's call stack in wow64cpu.dll . Here is the example:
wow64cpu.dll!0000000078b83f01()
[Frames below may be incorrect and/or missing, no symbols loaded for wow64cpu.dll]
wow64.dll!0000000078be6a5a()
I've got 3 libraries from that OS:
wow64win.dll wow64.dll wow64cpu.dll
I've downloaded the symbols files (*.pdb) from
http://msdl.microsoft.com/download/symbols for the first 2 libraries. Here is the same call stack after loading symbols for the wow64.dll:
wow64cpu.dll!0000000078b83f01()
[Frames below may be incorrect and/or missing, no symbols loaded for wow64cpu.dll]
wow64.dll!RunCpuSimulation() + 0xa bytes
But I can't get the one for the third - wow64cpu.dll. I've tried that in different ways. At first, by using Visual Studio (2008), and then by using symchk from 64-bit Debugging Tools, running on 64-bit Windows Server 2008. All with the same result: no symbols
file.
While using symchk on 64-bit Windows Server 2008, I've tried to download symbols for the local wow64cpu.dll (i.e. the one that is included in Windows Server 2008) - and have succeeded.
Here are the outputs form symchk for both libraries: the one for the 2003's library:
C:\Program Files\Debugging Tools for Windows (x64)>symchk d:\temp\000\wow64cpu.dll /s srv*d:\temp\symbols*http://msdl.microsoft.com/download/symbols /oc d:\temp\000
SYMCHK: wow64cpu.dll FAILED - wow64cpu.pdb mismatched or not found
SYMCHK: FAILED files = 1
SYMCHK: PASSED + IGNORED files = 0
... and the one the 2008's library:
C:\Program Files\Debugging Tools for Windows (x64)>symchk C:\Windows\System32\wow64cpu.dll /s srv*d:\temp\symbols*http://msdl.microsoft.com/download/symbols /oc d:\temp\000
SYMCHK: FAILED files = 0
SYMCHK: PASSED + IGNORED files = 1
Here is the attributes for wow64cpu.dll from Windows 2003:
File Version: 5.2.3790.3959 (srv03_sp2_rtm.070216-1710)
Product Version: 5.2.3790.3959
Modification date: 15 March 2007, 16:00:00
So, the questions are:
where is the symbols file? how to get it?

Hello!
I've already done that:
http://social.msdn.microsoft.com/Forums/en/windbg/thread/ba44ef7b-51a4-4660-ba60-7c8b27089d4e
At this moment, I haven't got an answer in that forum.
I've called MIcrosoft Technical Support Service and told them about the promblem. After I've told them that I've asked my question in
http://social.msdn.microsoft.com/Forums, they replied that it would be better to address it to this forums.
That's why I've posted it here.
