SharePoint 2007 on Windows Server 2008 R2
When you consider using Windows Server 2008 R2 for your SharePoint 2007 platform you need to put additional effort to configure and install SharePoint properly.
There are a few actions you need to undertake for the successful deployment of SharePoint on R2.
1) You can only install SharePoint 2007 SP2 on R2 version. Unfortunately, MS doesn’t provide SharePoint 2007 SP2 slipstream package, so you need to create one by yourself (Take into account, that you need to delete everything from the “\Updates” folder in case of using SP1 slipstream)
2) After you complete installation you will find that whenever you are trying to open the Central Administration the login and password are requested, regardless of your efforts to add Central Administration to the Trust Zone and set the option to logon automatically with the user’s name/password. This is a new change in security of Vista and Windows 7. To remove the login prompt you need to add a key “AuthForwardServerList” to the windows registry. Read the following guidelines.
3) When you create a new site and try to open it you can find the situation when login dialog box is prompted, but you end up with the white screen after you entering credentials three times. Usually, you navigate to c:\Windows\System32\drivers\etc\ folder, open the “hosts” file and add an alias for your site to solve this problem. But, under some circumstances this wont help you in R2, and moreover, your can’t open the site via “localhost” name. The solution is to add the alias not only to host file, but in “lmhosts.sam” as well
