How to rejoin a Client PC to a 2003 SBS Domain when i can't log on

Hi All,

I've recently changed my setup where the server used to be on a remote site and a domain connected client was in the office just connecting to the server for Exchange via HTTP.  the client was originally added and connected to the domain on the same LAN as the server until I moved the client to another office.

Today I moved the server into the office from the remote site, plugged it into the LAN and now only one of the 2 domain clients can communicate with the server.  I have a laptop here running Windows 7 Pro and it connected first time to the server and Exchange works perfectly. But my main PC running Windows 7 Ultimate, just wouldn't connect to Exchange. I tried creatig a new Outlook profile but the name wouldn't resolve to the server so I tried removing the PC from the domain and joining it again.  Now I've done that I can't even log onto the domain and I get a message saying " The security database on the server does not have a computer account for this workstation trust relationship"  I then logged onto the server, removed the PC in ADUC and tried adding it again, however this has not helped.

I now find myself in the situation where i can't even log onto the client as a local user and I can't log on as a domain user so my question is, can i fix this from the Server end alone?

The server seems to be working fine and the second client PC is having no problems at all.

Would really appreciate some help on this please.

What i would try :

- Log on localy on your W7 computer, setup a VPN to where the DC is
- Now that VPN is connected, you can insert computer into the domain
- reboot the machine
- Unplug the network cable (if plugged your computer will look after the DC)
- Select your domain, your old login account, now you should be able to log on your computer because of it keeping your old profile information before you removed it from the domain
- While connected with your AD profile, plug the network cable, setup VPN on this session, and connect it to make GP and AD updates.

Hope it works for you.

I dont know if you change your mind about what you want to do, but it's better appreciated to reward the effort of the person who answered your first concern than simply deleting your question.

I apologise if I've upset anyone on this, I deleted the question because the main part of my question was that I couldn't even log in as local user and the only answer that came back had the suggestion "log in as local user then...."  I very much appreciate anyone who takes the time to answer my questions but I didn't necessarily feel it was appropriate to award any points in this particular instance.  Many thanks for taking the time though Daelt.
