Hi.  Have a new SBS 2008 server which is all working nicely except that when I setup an external Outlook 2007 client, autodiscover sets everything up fine but gets the authentication wrong in the connection settings - ie Basic not NTLM.  Have been trawling the web for info but cant see the wood for the trees now...

So do you want to change the authentication on the client or server?
To change the authentication on the client:

1. In Outlook > click Tools > Account Settings
2. Click the Change button
3. Click the More Settings button
4. Click the Connections tab
5. At the bottom, click the Exchange Proxy Settings button
6. Under Proxy Authentication Settings, use the drop down to change authentication.

What I need is for the Autodiscover service to set this automatically to NTLM rather than have to go in there manually.  If I manually change it to NTLM all works fine.

Basic Authentication is the default which Outlook will use. What result do you get if you run a get-OutlookAnywhere|fl at Exchange Management Shell? (Post the result here).

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Have removed identity of server etc (replaced with -)

I can see it's showing basic.  So will Autodiscover automaticically use that value if I change to NTLM.  Is there a reason I should leave it as basic?  The RPC not found error is presumably because RPC is in SBS Web Applications rather than Default Website (which SBS did itself, not me (I hope)).

I've had my issues with this on SBS. Firstly, you'll need to patch with this hotfix: http://support.microsoft.com/kb/954034.

Once that's patched, I'd then run set-OutlookAnywhere -Identity "<value in the 'Identity' section of the get-OutlookAnywhere output>" -ClientAuthenticationMethod basic -IISAuthenticationMethods basic

Then, launch the TS Gateway Manager console from Administrative Tools > Terminal Services. Doing that will reset the TS Gateway configuration, and should get the two to co-exist.
