.NET returning incorrect username

Question

I made a spelling mistake when I created an account a few weeks back. I changed the account and they can log onto the domain with the new name. However we have a web application in house that is still picking up the wrong name.

The .net application uses

System.Security.Principal.WindowsIdentity.GetCurrent().Name;

Which gives the old name.

If I use

Environment.UserName

I get the correct new name. What did I miss in the AD? Is there somewhere I can change the name which will result in System.Security.Principal.WindowsIdentity.GetCurrent().Name; giving the correct name?

I have no experience with .net so I'm very sorry if the question has an obvious answer.

Add the Key:

"HKLM/System/CurrentControlSet/Control/Lsa/LsaLookupCacheMaxSize=0"

To your registry as this is cached. I don't think restarting IIS will fix this issue.
