ldap with Windows server 2003

Hi all,

First of all, machine

Server: Windows server 2003 sp2 Domain controller with active directory, dhcp server, dns server .

Clients : One is XP SP3 and one is win7.

There's the story. Server crash (motherboard died) so build new one on a rush. Got some problems but evertything seems now to be quite ok. This server run a c# app witch use ldap to get the group the users is in.

My only real problem is : With those 2 machine, it's impossible to log on. It tell me that the user or password is wrong. There is +- 30 machines (win7 and XP) who logged all day long without problems and on any of those who work, the user and password work perfectly.

I just dont understand why those machine wont connect. I'm not a network guy, i'm a programmer who is taking care of everything (like alot of people i guess) so my knowledge in this kind of problem is not that good.

Thanks for your help

EDIT: I forgot to mention those 2 computers communicate over vpn and are not on the same subnet.

There are a couple of possibilities.  One is that there are cached passwords on the workstation that are no longer valid.  You can check this by looking in Control Panel/User Accounts on the Advanced tab, then click Manage Passwords. This will show you a list of cached credentials and you can remove any old ones that might be causing issues.

Another possibility is that there is a problem with the computer account on the domain.  Are those two machines part of the domain?  In other words, when you look at the computer properties on the workstation, does it say it's a member of the domain at the main office or a member of a workgroup?
