Oracle 10G Net Config fails to start - installation issue on Windows in a domain

[Captain Obvious]

I'm posting this in hopes that it will help a few folks out when the search
Google Groups.

I was having the following problems with Oracle 10G:
1. When installing the database, the net config assistant would fail and I
would end up with no listener. Furthermore, I couldn't run Net Config to
create one.
2. I could not start the Network Configuration Assistant after a fresh
install of the 10G client on a workstation.

Problem:
It would appear that the Net Config tool checks to verify that your user
account is explicitly listed in the local Administrators group. In all
instances, I was logged in with a domain administrator account and Domain
Admins is listed in the local Administrators group. It seems Oracle is
checking for a name in a list rather than the effective administrative
permissions.

Resolution:
My findings are that even if you are a domain administrator, you must add
your individual domain user account to the local Administrators group on the
machine where you are configuring either the Oracle 10G database or client.

I also ran into problems with OracleCSService and I received some CRS error
during database installation. I'm not sure if this is related. I ignored
these issues since I didn't install in a clustered environment.
