Windows Server 2003 with IIS6 and ASP.NET 4 giving 404 error

[kylemcisaac]

I stumbled across an issue when trying to access the VaultService folder on my local server. When loading the page it would give the wonderful yellow page of death with a 404 message saying /VaultService/eurl.axd/guid (where guid would be a random 32 character string).

After researching this error, it seems that ASP.NET 4 and IIS6 have a small issue with Extensionless URLs. Resolution is done by entering the registry and navigating to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\4.0.30319.0. Upon entering this node, add a DWORD value of EnableExtensionlessUrls and set it to 0. Restart IIS and it should work.

Hope this helps.

Thank you for your post. This can also usually be performed in the IIS Manager under Web Server Extensions.
