PROBLEM DESCRIPTION
===================
On a Windows 2003 64bit machine with both .NET Framework 1.1 and 2.0 installed, you are tying to configure a website on IIS, but you are unable to find the tab to specify ASP.NET settings.
SUMMARY of TROUBLESHOOTING
==========================
Researched turned out this being a bug that is closed as "won’t fix".
If you are gong to run IIS 32-bits on WOW64, MMC Support for ASP.Net snap-in is currently not allowed.
We are in the process of writing a KB article to document this.
In general the ASP.net tab is giving you the UI to configure the application to run different versions. You could use the specific version of aspnet_regiis.exe utility to configure this.
The utility is aspnet_regiis -i under C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727, if you want your application to run under 2.0.
There are several command switches to configure specific sites or directory only.
If you see these problems on 32-bit OS there’s a known workaround:
- Manually run the install for ASP.NET: ASPNET_regiis -i
- Register the dll for the MMC: regsvr32.exe "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mmcaspext.dll" "rundll32.exe" "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\webengine.dll",RegisterAspNetMMC
- From a command prompt run: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm.exe C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\AspNetMmcExt.dll /tlb:AspNetMMCExt.tlb
- Change the About value in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\SnapIns\{fedb2179-2335-48f1-aa28-5cda35a2 b36d}" from {7D23CCC6-A390-406F-AB67-2F8B7558F6F7} to {7D23CCC6-A390-406F-AB67-2F8B7558F6F6}
