Once in a while, my Exchange 2003 server's transaction logs suddenly start generating at a frenzied pace of several per minute, leading to a full log file volume. Sometimes I've been able to determine from viewing a log in WordPad what sort of Exchange activity was involved, based on identifying key words among the mostly un-intelligible characters. This has helped me solve the problem. But sometimes there doesn't appear to be any intelligible text to go on. Is there a tool out there that reads transaction log files and will summarize what is in them? Or can you suggest another way to identify what activities a particular log file contains? Thank you!
