Very strange AD authentication issue

view story
linux-howto

http://serverfault.com – I have a domain controller that is Server 2008 and another that is 2008R2. I changed my password two weeks ago, and have been able to log into the domain controllers no problem. When I want to access any other server in the domain (the entire environment is nothing but IIS and SQL servers) I run into a strange issue. In the RDP client, I use my current credentials. Using anything else causes it to fail. Once I hit okay and it starts to login, the server I'm remoting into tells me that my credentials are incorrect, and from there I have to use my old credentials. Nothing in the logs aside (HowTos)

Stories similar to Very strange AD authentication issue

I've tried to figure it out for several months, with no success. I have a Windows 2008R2 domain, and one Linux server (first it was Fedora 15, then 16, and now it's Centos 6.2). I am trying to make it member of the domain to the extent possible. Ideally, I would like to login and get authenticated against domain (say, login 'DOMAIN+john').

We have multiple servers scattered over different hosting providers. For learning, experimenting and, ultimately, production purposes, I set one of them as a Domain Controller.

Environment:

Windows 2000 sp4 EDIT: Domain Controller with no trust setup with the Win2008 Server Windows XP machines Windows 2008 Server Netapp NAS

Problem:

We have a shared folder that resides on a NAS using a Windows 2008 AD for the authentication with the proper permissions setup.

I have a development server with an SQL 2008 EXPRESS instance running on it.

My work proxy server requires authentication with the Microsoft AD domain user credentials.

I'm managing about 20 computer for a small business, and set up their network yesterday. We have a server that fills multiple roles, including DHCP, Domain Admin, and file sharing/storage.

Today all of the computers have access to the internet and the server files with the exception of one.

I've ran into a strange issue. Our domain admin accounts, for some odd reason, aren't seeing certain files. It was mainly on three workstations that were off the network for a while for hardware repairs and were rejoined.

The three workstations are running 7 SP1. The respective Domain controllers that were used as logon servers are running 2008r2 x2, a 2008sp1, and 2003sp2.

I have 3 boxes.

DC = Domain Controller running Win2008R2 Client = Server running Win2008R2 joined to the domain Server = Server running Ubuntu 12.04

Kerberos is setup on "Server" to authenticate against Active Directory on "DC". kinit and klist work as expected.
