SysPrep windows 2008 r2 with IIS 7.5 installed with ASP.NET 4.0

Posted on 2014-03-08
Last Modified: 2014-03-15
I 'sysprep' an existing windows 2008r2 which had IIS 7.5 installed with ASP.NET 4.0 with two web apps configured

My concern is after I have done the  sysprep what config changes would this do to IIS already installed with ASP.NET 4.0 and two of my web apps.  

How would I know if the apps still function correctly, is there anything I could check ? Or would it be of benefit to remove IIS, ASP.NET 4.0 and the web apps and re-do the lot again ?

Please have a look at this link, seems it needs to be configured again after the Sysprep,

The following link may be considered for your update, It is for XP OS but still you can have a look

This article says that Windows 2008 and Windows 2008 R2 are Sysprep friendly with IIS.
I have used Sysprep on a machine that hosted a web site and ftp site and had no issues.

What does this mean:-

Web Server (Internet Information Services)
Not supported with encrypted credentials in the Applicationhost.config file.
Not supported with encrypted credentials in the Applicationhost.config file.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The Applicationhost.config file is file that contains your IIS settings. It's kept in C:\Windows\System32\inetsrv\config\ by default.

Do you have any sites in IIS7.5 that are configured to run under specific user accounts?
If yes, then are you using any encryption? IIS uses encryption for attributes that are marked as "encrypted=true".  If you opened the "applicationhost.config" file in notepad, you'd see those credentials you configured were indeed encrypted.

You would not want that Sysprepped to another machine. I think you'd have a problem.
If you're not using a specific user account to run your site(s) and not using any encryption attributes, it would be okay.

The only issue is we have SSL certificates installed, would these become invalid ?

I'm not 100% sure but it does sound a little risky. I wouldn't do it unless you can perform a small test first to prove it isn't a problem. Anything so account specific like an SSL may have problems after Sysprep. Personally, I wouldn't do it unless I tested and made sure it worked beforehand.
