You should be running 4.1.1.1d, since any previous version of the HL server
has a security hole, that enables other people to freeze you HL, crash your
HL, crash your machine or even take control of your machine!

Also, running 1.x.x.x as server (which means you are using the client as
server) is a bad idea, since it almost always lags behind in server
versions. Install the full dedicated Windows server instead.
