IIS 6.0 only: Set IIS to use NTLM authentication

Installing > Installing System Architect XT > Editing the web.config file > IIS 6.0 only: Set IIS to use NTLM authentication

This section applies only if you are installing System Architect XT on an IIS 6.0 server: you might need to configure NTLM manually with Integrated Windows authentication as the authentication mechanism.

If you use IIS 6.0 and the System Architect XT server does not work, use these steps to check your security settings are correctly set.

1 Click Start > Run, type cmd in the Open field, and then click OK.

2 Go to this directory:

C:\InetPub\Adminscripts

3 Run this command:

Cscript adsutil.vbs get w3svc/NTAuthenticationProviders

If the command returns this message, no further action is required:

NTAuthenticationProviders: (STRING) "NTLM."

If it does not return the above, continue with step 4.

4 Run this command:

Cscript adsutil.vbs set w3svc/NTAuthenticationProviders "NTLM"

5 Repeat step 3 to confirm the setting has been corrected.
