OWA 접근 시 'HTTP 500 - Internal Server Error' 에러 (Exchange Server 2003)

registered the dll C:\Windows\System\regsvr32 scrrun.dll
and restarted IIS by running "IISReset" from the command prompt

If the OWA still not work, please create a new HTTP Virtual Server and see
how it goes. To do so:

Open EMS, expand severs -> protocols -> HTTP, right click on it, select new
-> http Virtual Server.

Then, please right click on the new virtual server and select browse to
check if it work.
