No such thing as SQL 2003.
There are many ways to generate artificial primary keys (keys that have no meaning within the data), there's also the option not to use an artificial primary keys but rather choose one of the candidate keys from the data as the primary key.
Can you be a little clearer what you're asking?

Ok they have asked us to create a database which I have and now I need to create a table. They ask for event I'd to be unique and then ask for it to be auto generated

Can you be more specific?
What is the requirements for the EventID? What's it going to be used for? (if nothing, why do 'they' care about how it's generated)?

Without clearer explanations, we're not likely to have a clue either. Have you asked the teacher/lecturer?

That's all they ask me to do. Event I'd is an attribute in table. Which will be primary key. And now needs to be auto generated

Would still like to know who this "they" is.
Look up identity columns in Books Online.
