*HTTP 500 Internal Server Error

I saw the two winwdow service and both are running. When i go to the event viewer, i can see this error

<detail><string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">The user ID and password are invalid. Try again.</string></detail>

But is error is very strange because i connected with the administrator.

Hi,

Do you have the windows user Administrator like NAV user?
In order to work with NAV Web Service you must have the user (In your case Administrator) like a NAV user.

Hi,
Error 500 will not help you to solve the problem.

Try this http://support.microsoft.com/kb/218155/en.

1) Click Start, click Settings, click Control Panel, and then double-click Internet Options.
2) Click the Advanced tab.
3) Click the Show friendly HTTP error messages check box to clear it.
4) Click OK.

Yes, my user is a "super" user in Nav.

Hi,

have a look in you service config file. (Customsettings.config)

Set WebServicesUseNTLMAuthentication to false if it is true.

<add key="WebServicesUseNTLMAuthentication" value="false"></add>

You will be asked for a username and password. Try with a user which has the role SUPER.

When solving Error 500, do not forget to describe the infrastrucutre: is the WS serverrunning on same server as SQL? If not, have you set correct SPNs and enabled the delegation for the WS Server?

Two things you could try is use the computer-name instead of localhost, and make sure that intranet pages are trusted so Internet Explorer allows sending user credentials to the service.
