Recipe 15.1 Enabling Extended dcpromo Logging15.1.1 ProblemYou want to enable extended dcpromo logging. This can be useful if you are experiencing problems during the promotion or demotion process and the dcpromo log files are not providing enough information to indicate the problem. 15.1.2 SolutionThese solutions are slightly different on Windows 2000. See the Discussion section for more information. To enable the maximum amount of logging, use 16711683 (FF0003 in hexadecimal) as the flag value. For a complete description of the possible bit values, see MS KB 221254. 15.1.2.1 Using a graphical user interface
15.1.2.2 Using a command-line interfaceWith the following command, <FlagValue> needs to the decimal version (not hexidecimal) of the flag value: > reg add HKLM\Software\Microsoft\Windows\CurrentVersion\AdminDebug\dcpromoui /v[RETURN]
"LogFlags" /t REG_DWORD /d <FlagValue>
15.1.2.3 Using VBScript' This code sets the dcpromoui logging flag (for Windows Server 2003 only) ' ------ SCRIPT CONFIGURATION ------ strDC = "<DomainControllerName>" ' e.g. dc01 intFlag = <FlagValue> ' Flag value in decimal, e.g. 16711683 ' ------ END CONFIGURATION --------- const HKLM = &H80000002 strDcpromoReg = "Software\Microsoft\Windows\CurrentVersion\AdminDebug\dcpromoui" set objReg = GetObject("winmgmts:\\" & strDC & "\root\default:StdRegProv") objReg.SetDwordValue HKLM, strDcpromoReg, "LogFlags", intFlag WScript.Echo "Dcpromoui flag set to " & intFlag 15.1.3 DiscussionAs described in Recipe 3.5, the dcpromo wizard creates a couple of log files in %SystemRoot%\debug when it is executed, which can be useful in troubleshooting promotion or demotion problems. Typically, the default amount of logging that is done in the dcpromoui.log file is sufficient to identify most problems, but you can increase it as described in the Solution section. The location of the log flags registry value changed from Windows 2000 to Windows Server 2003. In Windows 2000, the value is located here: HKLM\Software\Microsoft\Windows\CurrentVersion\AdminDebug\dcpromoui In Windows Server 2003, the value is located here (which was used in the Solutions section): HKLM\Software\Microsoft\Windows\CurrentVersion\AdminDebug\dcpromoui\LogFlags 15.1.4 See AlsoRecipe 3.5 for more on troubleshooting dcpromo problems, and MS KB 221254 (Registry Settings for Event Detail in the Dcpromoui.log File) |
