During the Exchange 2000 setup or upgrade process, Setup may stop, and an error regarding the registering of Exoledb.dll is displayed. In the Exchange 2000 Setup log, you may receive one of the following error messages:
regsvr32 /s exoledb.dllfailed, returning error code 5 (Access is denied).
Setup failed with 0xc103798a registering the base dav protocol.
This error may occur if the .dll files, upon which the Exoledb.dll file is dependent, are not registered.
To work around this error, manually register the dependent .dll files (Msdaurl.dll, Msdaipp.dll, and Oledb32.dll) by typing the following command from a command prompt where name.dll is the name of the .dll file that you want to register:
regsvr32 name.dllFor example, to register the Msdaurl.dll file, type the following command from a command prompt:
regsvr32 msdaurl.dllGenerally, the Msdaurl.dll, Msdaipp.dll and Oledb32.dll files are located in the %SystemRoot%\Program Files\Common Files\System\Ole DB folder. You need to run the regsvr32 command in the directory in which the .dll files are located.
After you register these files, you can click Retry in the Setup dialog box to allow Exchange Setup to register the Exoledb.dll and continue with Setup.
