Question on demoting virus infected SBS 2003 then promoting clean 2008


I have a client who has been fairly careless with their network security.  I have done what I can but now we have a serious virus infection on both the single SBS 2003 server and the five (5) XP SP3 clients.

I have tried to clean them up as much as possible but all of the machines have sustained some damage (deleted dll's etc) including the server.

I have been asked to replace the server with a new SBS 2008 server which is required for their new office software (not Office) .

If I clean the systems up as much as possible using what every tools I can, is there a way to do the automatic migration from the SBS 2003 server to the SBS 2008 server without causing the 2003 server to shut down.

What we would prefer to do is perform what ever actions are required by MS to migrate from 2003 to 2008 while maintaining the original 2003 server as a backup in case the migration fails.  My understanding is that the natural migration process leaves the 2003 server unable to boot.

Am I correct in my understanding?

The 2003 server does not provide any real functionality other than hosting a shared drive, printers, fax, and support a database (Pervasive) and an interface to the database.  It does not support any other activity other Exchange functions.

Given this, is there a simple way to do the migration that will incur lower risks?

Mind you I am not in any way an expert on MS server - this is my first migration effort in a small business.

Thanks for the help.

You can only have ONE SBS server on a network.  You CAN have other servers, but only one Small Business Server "class" system.  So at the end of the Migration, you will need a new license for the SBS 2003 system if you want to continue using the hardware.

Given that your network only has 5 clients, I would start clean.  It shouldn't be too terribly difficult to start from scratch and it should allow you to help ensure the health of the network overall.

If you haven't installed SBS before, I recommend doing a few (2-3 at least) test installs to get familiar with it.  I would dare say you're doing your client a disservice if you setup their system as the first one you've ever done.

That is pretty much were I was.  It is not the first system I have set up, however it is the first one in which the client has wanted to migrate via the MS tools.  Historically when new hardware was required we would reevaluate the requirements and make adjustments which generally meant we would start from scratch.

The question is, can the database information be trusted.  We have been using AVG in the past, mostly because of compatibility issues with Zone Alarm and Norton not liking the other tools required by the office as well as limitations with SBS Server.  We are open to suggestions on anti-virus tools both hardware and software.

I would never recommend Norton - they are a FANTASTIC company - AT MARKETING.  As far as programming goes, their software causes WAAAAAY too many problems.

As far as antivirus/antimalware, I've been suggesting VIPRE Enterprise to most of my clients.  But basically, they all stink.  15 years ago, antivirus caught 99% of all possibly infections.  Today, it's more like 80.  Software protection is a necessity, but it's more critical than ever to manage user expectations - AND to properly educate users and use multiple defenses (such as a UTM device on the perimeter).
