Domain Unavailable

Power went off overnight , I now have an issue where only a couple of people can logon from the domain in the office and open Outlook 2007, whereas most of the users just get domain unavailble. External users using webmail have no problems and I can access and ping the server and all the relevant services are running as we have some staff using Outlook in the office  so whats gone wrong for the rest of us. Any Ideas

are you able to ping the server from the machine where domain is not available. when power failure were there the client machine also restarted or only server. it could b h/w as well as s/w problem also, run netdiag also see what the result is. you may find some faq on microsoft also. here is the link.

it's hard to say without being on-site to look at the issue.  It could be any number of things, but here's an idea.  Everything lost power overnight.  The server boot up is a relatively lengthy process.  PCs would boot up more quickly.  PCs power up, but there is no DHCP server available since the server is still booting.  PCs come up and have no IP address.  

Suggestion - reboot the office PCs now that the server is fully up to get an IP address.

in addition to this, it could be machine nic port issue also, i came a cross for one of my client. They were using the systems when thundering, suddenly power goes off, and next day found 14 machine nic went bad, thanks to warranty, all the MBD has been replaced.
see if the issue is similar to this.

-ping the server from a client if that next step if not run ipconfig to see if they have a valid IP if so reboot all switches, you may have a locked port/s
-if ping works, run nslookup server.domain.loca from a client and see if it is a DNS issue. If this fails, check the event log of the server and look for any possible corruption of Active directory

Sorry Colleagues, I have been very ill and unable to do anything. I had already tried all your suggestions. The issue is ongoing however I have a workaround which was to create a Workgroup so sharing can work and connect printers by USB instead of network.
We are having a hardware refresh in the next few weeks therefore the problem will be completely resolved and I can finally put to rest the SBS 2003 server.

The solution I am going to adopt and this is only because of a hardware refresh is to rebuild my servers.
Thank you for your suggestions but I had already tried all of those and since I was very ill - I couldn't get back to you.

All the previous comments, whilst acceptable - I'd already tried. I was then VERY ill for 3 weeks and still a resolution was to be found. Now that we are having a hardware refresh. The chance to rebuild the domain from scratch is there. A Draconian way to do it but until a real solution is still to be found this is the way I have to do it.
