摘要:Windows Messenger 5.0有一个注册表项设置,可以用来启用日志文件,该文件中记录了Windows Messenger 5.0登录LCS Server的详细来往包,可从其中得到通讯细节,从而作troubleshooting。
MS KB文章详见《http://support.microsoft.com/default.aspx?scid=kb;EN-US;871023》
步骤是:
第一步,运行regedit;
第二步,找到注册表项:
HKEY_CURRENT_USER\
Software\
Microsoft\
Tracing\
RTCDLL
第三步,在该项下,找到名为EnableFileTracing的DWORD项,将其原来的数值0改为1,表明启动文件日志;
第四步,重新启动Windows Messenger 5.0/5.1,登录LCS 2005服务器;
第五步,到“%USERPROFILE%\Tracing”文件夹下察看日志,比如说我的日志文件在“C:\Documents and Settings\VictorZheng\Tracing”文件夹下的一个“RTCDLL0.log”文件。
这个文件中记录了WinMsg登录SIP Server的详细来往包,可从其中得到通讯细节,从而作troubleshooting。
第六步,最后要将“EnableFileTracing”项数值改回为0。
从该日志文件可以看出:
具体的包体示范如下:
