IIS 7.5 Windows Authentication Error Using 401

Since we upgraded from IIS 7.0 to IIS 7.5, Windows Authentication no longer works with remote requests. If I open the site on a web server, everything will be fine.

web.config:

<authentication mode="Windows" /> <identity impersonate="true" /> <authorization> <deny users="?" /> <allow users="*" /> </authorization>

IIS Settings:

 Authentication (enabled): ASP.NET Impersonation, Windows Authentication (all others are disabled) ApplicationPool: Managed Pipeline Mode -> Classic, Identity -> ApplicationPoolIdentity

Request failed:

 MODULE_SET_RESPONSE_ERROR_STATUS ModuleName: WindowsAuthenticationModule Notification: 2 HttpStatus: 401 HttpReason: Unauthorized HttpSubStatus: 1 ErrorCode: 2148074254 ConfigExceptionInfo: Notification: AUTHENTICATE_REQUEST ErrorCode No credentials are available in the security package (0x8009030e)

Any suggestions?

We had a problem with two hopes, I think. If I transfer our SQL / Oracle database to a server running IIS, it works.

So, here is an article that describes the solution.

Which client are you using? you can run a client that attempts to perform pre-authentication, but in IIS 7 we use kernel-mode authentication by default, which requires a call. If so, you can disable kernel mode authorization by selecting the Windows Authentication entry and clicking "Advanced Options", you must select a check box that allows you to disable it for a specific application, and it should work if this is a problem.
