Error Connecting To Express Using Sql Management Studio

Hi,

The issue,

I have had SQL express installed and working ok, however, I can no longer connect


OS: XP sp2.0

.net installed
ver1.1 .. 2.0 sp1, 3.0sp1 and 3.5

The install of SQL was using the SQLEXR_adv download

I have removed SQL and all associated applications folders and windows SQL services

I have re-installed many times but always receive the same issue.

I re-built the .net 2.0

The issue I have is when I try and connect form my applications or with Express sql management studio I receive the following error:

It looks like a .net2.0 issue
