In order to run installation on windows 2008 machine you need to perform following set of activities.

First download WSS Service Pack 1 and Office Sharepoint Server 2007 Service Pak 1 from Microsoft site.

Copy all files from installation CD to local disk.

Open command prompt and navigate to folder where you have downloaded service pack1 for WSS and Office server and run following commands
wssv3sp1-kb936988-x86-fullfile-en-us.exe /extract:C:\WSSSP1
officeserver2007sp1-kb936984-x86-fullfile-en-us.exe /extract:C:\MOSSSP1

Copy all files you extracted in last step i.e. C:\WSSP1 and C:\MOSSSP1 to Updates folder of Sharepoint installation (at local disk)

Sharepoint - How to design printer friendly pages

I was thinking about adding support for printing my content pages in my share point site. As I have done this before in my custom side so I utilize same idea for hiding content displayed in my master page in print view. I created a css file and published in my style library and add css link in my master page with media set to print

<link href="[cssfilelink]" rel="stylesheet" type="text/css" media="print" /&gt

Then I added following 4 css classes in my stylesheet. After finishing this when I print my sharepoint page from browser it autmatically removed master page section and print only content area.





Any suggestion or better strategies for achieving above is welcome
