Microsoft SQL Server If you have not already installed Microsoft SQL Server Version 7 0 or later do so now When SQL Server asks how many licenses you own you will need as many licences as you expect simultaneous connections Serf runs very fast however and just a few connections can service hundreds of users Experience has shown that Serf runs just fine and can support a large number of users with the ten client licenses that come with SQL Server so you need not purchase additional client licenses for Serf Setting the number of licenses to 10 should suffice for most installations If you need more consider purchasing the SQL Server Internet Connection License through the Microsoft Select Program If you get any error messages during the installation reboot your computer and reinstall MS SQL Server until you get a clean error free installation Page 4 Serf Sysadmin Guide 3 Creating the Serf Database After you have installed Microsoft SQL Server you use SQL Server to create the Serf database Follow these steps From the Windows Start button choose Programs Microsoft SQL Server gt Enterprise Manager to get the Enterprise Manager running Expand the server tree to reveal the databases currently installed under SQL Server If this is a new installation you will see the Master and Tempdb database and two demonstration databases named Northwind and Pubs To create the Serf database right click Databases and when the menu pops out

You should study this booklet first then read the Serf Administrator Guide Installation Serf is coded entirely in Microsoft C NET and SQL Server Serf will therefore operate on any computer that has the NET Framework and Microsoft SQL Server Installing Serf is a xx step process that involves installing the NET Framework and SQL Server if the computer does not already have them creating the SQL database in which Serf will store its records running the Serf setup module which installs the Serf application creating some working folders in which Serf will do its work and providing Serf with access to these folders Important These instructions assume that when you perform the installation you are logged on to your computer as the system administrator 1 Installing the Operating System Serf was developed for the Microsoft NET Framework If the server on which you plan to install Serf does not already have NET installed you must begin by installing the NET Framework which is available as a free download from http msdn microsoft com netframework downloads howtoget asp All you need is the runtime version which is about a 21 megabyte download You should also download and install the latest service pack for the NET framework Please note that if your server is running Windows 2003 the NET Framework will already be installed because NET is an integral part of Windows 2003 2 Installing Microsoft SQL Server Serf requires
