Does anyone know where I can define this URI parameter?

Answer 1

I assume that you're using VSeWSS 1.3 to deploy you solution and that these error occur when you try to deploy the solution. I'm not 100% sure but I think I had the same error some time ago. Unfortunately I could remember what I exactly did to solve this problem. But I'm quite sure the problem was related to some network issues as VSeWSS 1.3 uses web services to handle solutions.

So I would advise you to double check you network settings. For example you could try to adjust your hosts file so that your computer's name could be resolved.
