Should ASP.NET v2 IIS server extension be missing after .NET 4 is installed?

Question

I'm having a ton of issues when my ASP.NET sites are using version 2. For example, all my SVC and ASPX files return "file not found". Also when I use IISMgr and navigate to:

ServerName
..... Web Service Extensions

I notice that no ASP.NET v2 is present. I tried aspnet_regiis but no luck. Any ideas?

UPDATE

Running aspnet_regiis.exe – i seemed to now have worked. But I'm still having issues with WCF. I just tried reinstalling WCF using ServiceModelReg -i and I get this in the event log

Also, this is what ServiceModelReg -ls looks like (note no Web Host Script Mappings exist)

No, this is not normal; you should have three ASP.NET externsions there: 1.1, 2.0 and 4.0.

Which aspet_regiis did you try? The 2.0 one or the 4.0 one?

Is this a x86 or x64 server?

For x86, run C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir.

For x64, run C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -ir.

AWESOME, That worked! It's back. I just ran ServiceModelReg to reinstall WCF, and it says I have no Web Host Script Mappings. Does that make sense? – makerofthings7 Aug 21 '10 at 18:54
The command I used was: C:\WINDOWS\Microsoft.NET\Framework\v3.0\Windows Communication Foundation>ServiceModelReg.exe -lv – makerofthings7 Aug 21 '10 at 21:03
Is there a reason you didn't mark this as the answer? – GregD Aug 21 '10 at 22:05
WCF is still broken, but I can create a new one for that... – makerofthings7 Aug 21 '10 at 22:46
