Sql Server 2K5: How do i replicate database?

I'm lost.  We have Sql Server 2005 on a remote box (A) and the local pc (B).  Both servers have a single database on them.  We've been copying the database A to B for some time and its becoming tiresome.  I've heard of replication but couldnt figure out what the MS site was saying.

How do i go about making a differential copy of the A database onto B?  

Thanks

How much data needs to be transfered?

Can't you make use of linked servers and write a stored procedure to transfer the data? Something like

INSERT table_b(a,b,c)
SELECT a, b, c
FROM serverB.dbB.dbo.table_a

Or is it too much data/tables to write sp for?

1. Open up SQL Server Management Studio
2. Connect to Server 1 (the database you want copied)
3. Expand the server folder structure you will see Replication
4. Expand the replication folder
5. Rght click and create a new publication under Local Publications
6. Once complete you can configure the distribution by right clicking on the replication folder
7. Connect to server 2 (where you want the database copied)
8. Under the replication folder if it has not already created a subscription to the publication on Server 1 create it.

Creating a linked server should only be used if you need to do cross server queries. 

If he just wanted to copy the data fresh everytime you could just setup a dts job that runs x number of times per day.

The option is up to you.  The replication will be faster because it will transfer less data.  DTS will be the whole package everytime.
