It is surprisingly interesting to see how many problems I have resolved as soon as I removed the .NET framework 1.1 from a server, when all the rest is working on 2.0. Today again, one server stopped responding to 2.0 Web Services. As we no longer need 1.1, I removed it, based on my experience that this has resolved a tons of problems in the past, and again it resolved the issue. Am I the only one that 1.1 is not happy to work with? :)
