Server help - BOpenService failed

I’ve been trying to configure a dedicated server for a few hours, and I ran into an error that I can’t find a solution to.

Can anyone tell me what to do?

I’m running the server software on an old XPS with an Intel Core2Duo and 4GB RAM, using Windows Server 2008 SP1 x64.

I am confident that nothing is wrong with the port forwarding, by the way.

Nothing? God damn it.
