Bingo.  The failing ones are auth'ing against the R2 DC.  The working ones are 
doing it against the 2008 servers. So I have gotten caught up in a new NTLM 
setting on R2 that I have just started reading about.

Hmmm....what DC(s) are the failing machine accounts authenticating against?

Ok, DC name resolution was red herring. Maybe.

The issue is desktop related.  XP workstations.....on some they fail and on 
others they are just fine using the same user account.  They all have the same 
group policies and same service pack (3). Now to check the desktop patch levels.

Cool, please do update us either way. Since you still have one DC that is not @ 
R2, I would not at all be surprised if that is the culprit or at least part of 
it.

Happy Friday!

I think you nailed it. I still have one 2008 DC running....and it is my primary 
DNS/Wins server for the IIS server in question.  NBLookups from the IIS server 
to one of the DC's is failing....got lots of bad WINS records in it. It was 
going to be decommissioned next week, I have moved that up to the end of the 
day today and I bet that  gets it.

I will certainly post a resolution if that is it.

Shot in the dark, since you say the failed attempts are being rejected 
locally...

Are all of your DCs talking to each other and updating/replicating with each 
other properly since you did the upgrade?

Subject: Intermittant IIS logon issues.


App on a 2003 IIS server that uses the IIS integrated authentication. The app 
does not do the authentication, the IIS website does. Authentication is back to 
2008 R2 DC's. And I think that is the issue, this seems to have just started 
when I updated the DC's from 2008 to 2008 R2.

It is very odd, some users can hit it with integrated authentication and others 
cannot.  For a couple of days at a time those that cannot sometimes can. When 
the users fail I can see it in the security log, that the user is being checked 
against the local server account list...rather than the domain. If the user 
hits the popup with domain/user at that point it authenticates them just fine.

Authentication methods on the website appear correct, and have not been changed 
since the app was setup.  Anonymous is allowed and the IUSR account is valid 
and synced up correctly. Then only Integrated Windows Auth is checked.
