While installation of Sharepoint (MOSS) you may face certain issues. In this post, I would just point you to some of the files which may be useful in order to troubleshoot the set up problems. First things first... you can configure it!

To do that, you need to edit the appropriate Config.xml file in one of the folders below (found in your installation folder). By default, it is

<Logging Type="verbose" Path="%temp%" Template="Office Server Setup(*).log"/> which means it won't overwrite your setup files, no matter how many times you do the setup. So, if you are troubleshooting any issue, you need to ensure that you are looking at the latest log file.

All the other log files except the Setup are kept in HKEY_LOCAL_MACHINE\Software\Microsoft\Shared Tools\Web Server Extensions\12.0\WSS\LogDir.
