When preparing to install SharePoint, ASP.NET v2.0.50727 must be set to a status of allowed in IIS Web Service Extensions. If this item is not in the list in IIS, navigate to:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727> or
C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727> for 64 bit
At the command prompt type: aspnet_regiis - i
Go back into IIS Manger and it will show in the list and you can set it to a status of Allowed.
Symptoms:
- Error message after failed install: "iis could not be installed on this server"
- The configure your server.log is:
Configurations for an Application Server
IIS could not be installed on this server.
To install IIS, try running the Configure Your Server Wizard again, or use Add or Remove Programs.
- When checking the iis6.log in the Windows directory this error appears:
OC_COMPLETE_INSTALLATION:iis_core:MyMessageBox: Title:IIS Setup Error, Msg:CoGetClassObject
0x80040154=Class not registered
- When trying to connect to a server in the IIS Management Console, an error message saying that IIS needs to be version 4.0 or greater
Solution:
- Uninstall all versions of .net framework and service packs
- Uninstall IIS through Add/Remove Programs
- Reinstall IIS
- Reinstall .net frameworks as needed
It looks like this is a .net error and removing the framework removes the error, then IIS can successfully install.
