Towards the end of the installation, i get the following error:

Enterprise manager configuration failed due to the following error -
Error starting Database Control
Refer to the log file at {oracle path}\cfgtoollogs\dbca\{db}\emConfig.log for more details.
You can retry configuring this database with Enterprise Manager later by manually running {oracle path}\bin\emca script.

Current platform is WinXP, but is has happened previously when i tried to install this on Win Server 2003.
Other websites suggest that its a time difference, but it doesnt seem to be the case here.

Took me a while to get this fixed before, would anyone know why this would happen?
