The server currently have .Net Framework 1.1, 2.0, 3.0. I've read from other sites that older version of .net needs to be uninstall if i need to remove the 3.5 SP1. I would like to have some information from people who have experienced this already. Help will be greatly appreciated http://blogs.msdn.com/b/astebner/archive/2008/08/01/8803442.aspx

Hello Martina_Miskovic and Fiona_Liao, Thanks for the help. I would like to ask if this applies for a standard and clustered set up of exchange.
