I have a test SharePoint server that is having a weird problem. When I try to browse to my home page from the server itself, I can access the site. However, I cannot log in as a different user nor can I log in as my original user afterwards. Also, when I try to browse to the site from my computer, I am prompted for a username and password. I enter my credentials, press enter and the login dialog appears again. This happens three times and then the browser window gives me a blank screen. Here's the weird part, I can log in just fine when I use Firefox.
I have checked the ULS logs and don't see anything there. When I checked the Windows event logs, I see four Audit Failures all with the following information:

This event is generated when a logon request fails. It is generated on the computer where access was attempted.
The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.
The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).
The Process Information fields indicate which account and process on the system requested the logon.
The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
- Key length indicates the length of the generated session key. This will be 0 if no session key was requested.
I've compared the settings on my test server with my live server and cannot figure out what the difference is.
