Applications load very slow on Windows Server 2008

view story

http://serverfault.com – I noticed the following loading time on Windows Server 2008 (32 bit) which is bothering me Sql Server Management Studio (2005) is taking a way long to load. Splash screen remains for more than 30 sec before I can see the connection dialog. In the past it used to take 1-2 sec. Once I connect to DB, all operations are fast. If I double click on any .config file, visual studio will open it. I can see visual studio launched instantly but it takes almost 20 sec before I can see the file in an editor. it started happening recently. Could anyone please direct me where to look for the solution to (HowTos)
