Moving NTLM Authentication to another server

Posted on 2009-04-23

I'm currently using NTML on a Windows Server 2003 box to authenticate Cognos BI users.  The server has been acting real flakey, so weve purchased a new server that also has Windows Server 2003 as its OS.  Can someone help me to figure out how to move the NTLM users for the old server to the new server?  

A little more background on my situation:  Many of you may be wondering why we dont user AD.  The reason for this is that our IT team is planning to restructure our AD forest and according to Cognos consultants, this could cause problems for us.  So that is why we decided to go with NTLM authentication.

Any help you can provide will be greatly appreciated!

    nice catch:

    I helped someone with this in the past:

    You can do this by GPO or manually.

    Thanks for the reply but I don't think that's what I'm looking for.  I'm not worried about the security portion of NTLM because I'm only using it as a third party authentication tool for Cognos BI software (Cognos doesn't have their own authentication built in).

    So...I'm just trying to get the user profiles that were built on NTLM transferred from the old server to the new server.  It's going to really suck if I need to rebuild profiles for 300+ users.

    In that case, your domain should Allow NTLM authentication, I think you can use the same GPOs as described.

    Then, you can replicate your users from one system to another after promoting the one server to a DC.

    NOTE: 2003 server SP2 is, I think, the cutoff point for NTLM,

    I am going under the assumption that CONGO uses the DC's as their authentication server and is a legacy program that requires NTLM authentication, not has its own authentication as you mentioned.


    Accepted Solution

    The server using NTLM has nothing to do with the DC.  NTLM authentication is just used by Cognos and is set up on the same server that Cognos is install on.  

    I found an app that may help me do this.  Just haven't had time yet to do so.

    Let me know if you have any other ideas.  Thank you for your help!
