When using symbols of Kerberos DLLs on Windows 2000, the debugger reports a warning that there is a mismatch in the checksums between the symbol and the corresponding executable image.


Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.


The symbol files of some Kerberos DLLs on Windows 2000 have incorrect checksums in the headers. The following are the binaries which checksums are incorrect in the corresponding symbol files.

  • Rsabase.dll
  • Dssbase.dll
  • Rsaenh.dll
  • Dssenh.dll
  • Gpkcsp.dll
  • Slbcsp.dll
  • Schannel.dll
  • Msv1_0.dll
  • Kerberos.dll

Even though the symbol file checksums are incorrect, the symbol information is valid and can be used for debugging.

Also, the symbols of Kerberos.dll require the symbol path (sympath) to be set to the DLL directory containing the symbol file. Usually the sympath will be set to the symbols directory and the debuggers will look in the corresponding child directories to find the symbol file. But in this situation only Kerberos.dll requires the symbol path to point to the DLL directory.
