login failure to Fortress server using Fortress client

[scadaguy77]

I am receiving the following error message when attempting to connect to Fortress via the Fortress client:

Unable to connect to http://webserver:8080/VaultService. No server was found at the specified URL. Please verify your network settings using the Options dialog under the Tools menu in the Vault GUI Client. Web Exception: The request failed with HTTP status 401: Unauthorized.

The server address is correct. The login is correct. Both verified by using Firefox and navigating to "http://webserver:8080/VaultService/Vaul ... fault.aspx". I restarted IIS on the target server, but no change. Please help as we cannot checkin or checkout our applications.

Client version is: 1.0.4 (15848)
Server version is: 1.0.4.15848

So you were able to connect before, but now you're getting this error?

Has something changed on the Vault Server machine or in IIS?

Did you recently do any Windows Updates on the Vault Server machine?

What operating system is the Vault Server on?

Yes. We were able to connect until very recently. I do not know of any patches applied to the server. It is running on a Windows2003 SP2 box. Currently we have no PDC in our network, only a BDC.

Verify that Anonymous Access is enabled for the Vault Service website in IIS. Open IIS Manager, and right-click on VaultService. Select Properties->Directory Security. Click Edit in the Authentication and access control section. Then check "Enable anonymous access."

Enable anonymous access is checked. See screenshot. I also attached output from the IIS diagnostic tool on the server.

You have Anonymous Access enabled, but based on the Microsoft Diagnostics errors, the IUSR_<servername> account isn't able to login because of a password error. Could the password have expired or did someone make a change?

The IUSR account is created when you install IIS. It's a built-in account for anonymous access to Internet Information Services. So there's some type of IIS configuration issue here.
