Both ASP.NET and PHP (and/or Java)

[Parmenides]

How much likely are you to get jobs if you know both ASP.NET and PHP as opposed to only one. (comments on other server sides welcome too)

Big points for the HR in sifting through through the resume pile? Not a big deal. Small edge?

Java and .NET are both in huge demand. Though projects are done in all sorts of languages.

Just depends on what you want to do, where you are located, etc. There are a lot of variables.

The only places where it would likely help is a consulting firm that has people work on a variety of different projects, or at a company where the IT department is disjointed enough to use both. The first is probably more likely than the second.
