I have upgraded my Windows 2003 SBS to .net 2.0.
Following the upgrade i get the following error message "Web Part Error: This page has encountered a critical error. Contact your system administrator if this problem persists" any page I try to goto on my "companyweb" site.

If I change the ASP.NET version on my companyweb virtual service in IIS I get an error about not being able to run two different .net versions on the same server

.NET 2.0 is not an "UPGRADE" to .NET 1.1, so did you install it for a particular application you added to your server?

Because none of the default SBS web sites are able to run on .NET 2.0.

If you don't have any need for it, uninstall it, and then you must re-register .NET 1.1 by running the following command:

C:\>WINDOWS\Microsoft.NET\Framework\v1.1.4322\  -i

I have installed it and registered it.
I have an application that does need it and when I have tried to run that application in .net 2.0 and the rest in .NET 1.1 I kept getting the error message that I can not run two different .net versions on the same server process.

At the moment, except for sharepoint, all the other default SBS web sites seems to be working fine.

If you need to be running .NET 2.0, then you create a separate Application Pool for that site.  You can't mix 1.1 and 2.0 in the same Application Pool.

Thank you Jeff
I have created a separate application pool and a new virutal server rather than creating virutal directory for the application yet I am still getting the error message

Sorry, I totally clipped the command line in my initial comment to you.  

The command to run is

C:\>WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

Please try running that and see if it resolves your problem.  If it doesn't, run it with a -r instead of -i, and then follow that by running it again with the -i switch.
