All, We are planning to install the .NET Framework 3.5 SP1 on our Windows 2003 Servers (Standard , Enterprise & Data Center) holding different applications on different servers (Exchange 2003 , SQL 2005, Visual Studio .NET). Please give me some input whether installing this software on my servers will impact the server or application performance issue. Also share if we have any known issues. Purpose of installing the .NET framework on my servers, since it's a prerequisite for installing Double Take Replication Software 5.2.2.1771.2 Standard Edition (Build - 5.2.2.1771.2.S) Regards, Karuna
