windows 2003 sp2 exchange 2007 server
When I add a new machine to domain and install outlook we cannot login to outlook it keeps asking for username and password.
Old machines work fine.
Recent change was removing AD and DNS service from exchange server and putting in on a separate win2k3 server.

Only warning on Exchange server

source: MSExchange ADAcess
category: Validation
eventId: 2159

Process edgetransport.exe (Transport) (PID=4360). Configuration object CN=Interop RGC,CN=Connections,CN=Exchange Routing Group (DWBGZMFD01QNBJR),CN=Routing Groups,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN="ourdomain",CN=Microsoft Exchange,CN=Services,CN=Configuration,DC="our domain",DC=an read from "new PDC" failed validation and will be excluded from the result set. Set event logging level for Validation category to Maximum to get additional events about each failure.  

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

On the workstation I see a error

Source: Kerberos Error
Category: none
EventID: 4


The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/"our PDC". This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly this is due to identically named machine accounts in the target realm(dour Domain"), and the client realm.

However I can attach to shared folder on the exchange server with no problem. The only thing that does not work is outlook.
I can even acces Exchange via OWA on this machine.

Checked DNS no error.
All servers and workstations have DNS pointing to DNS/AD server.
