Problemas ao Publicar o site no servidor!

Salve, Salve galera!

to com um problemão, fiz uma aplicação que funciona normal, quando é rodada pelo vs.net 2005 na minha máquina, porém quando coloco no servidor, indica que a "System.Web.Extensions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'" não foi encontrada, o problema é que em nenhum momento no meu web.config eu faço referencia a essa versão do System.Web.Extensions.

Resumindo ele diz que não encontrou a versão 2.0.0.0, mas eu no web.config só faço referencia a versão 1.0.61025.0.

alguém sabe oq pode estar acontecendo!?

esse é o link do erro...
