Changing the size of your distribution manager logs in SMS 2003
When having distribution manager issues with your sites or distribution points, you may need to increase the distribution manager log size. Using RegEdit , open HKLM \Software\Microsoft\ SMS \Tracing\ SMS _Distribution_Manager Edit the MaxFileSize (default is about 2.5 MB). Note how far back your log goes, and do some simple math to figure out how big to make it. If your current log is a day worth of activity, and you need 3 days. I suggest making it around 10 MB.
