Is it worth debugging a version that is more than 3 years old? A lot have been fixed since then. tcnative-1.dll is Tomcat Native library It can be downloaded here: https://tomcat.apache.org/download-native.cgi The tomcat-native-1.2.16-win32-bin.zip file has *.pdb files in it. Tomcat 7.0.55 was shipped with Tomcat Native 1.1.31. Those binaries can be downloaded from an archive website. I do not know whether they contain debug symbols or not. tomcat7.exe, tomcat7w.exe are renamed Prunsrv.exe and Prunmgr.exe from http://commons.apache.org/proper/commons-daemon/procrun.html http://commons.apache.org/proper/commons-daemon/download_daemon.cgi -> Browse native binaries download area... -> windows/ There are no debug symbol files in the current version (commons-daemon-1.1.0-bin-windows.zip).
