If you re-add your server on the Forward Lookup - add the FQDN servername.domain.domain and your server IP manually and it should resolve your problem. You need to do the same for Reverse Lookup too. As to why this has happened it's unclear.
thanks michael. i was scratching my head too. im going to have to do this after school has finished! from what i can gather i will have to delete the whole zone and recreate is that what you are saying
No you shouldn't need to do that. Highlight the nameserver and click Edit, then re-enter the required info on both Forward and Reverse Lookup zones. No server reboot will be required and your clients should start working again pretty quickly, unless there are any other issues.
well i know about the time server, im going to sort that one out now,
the PDC im not sure how im going to do this, ive run another DCDIAG.exe and it says the server holding the PDC is down,
i used to have another server within our school but it went down. this was a few months ago. you dont think its still trying to find the old server is it?? how to i get this server to be the PDC server
sorry to be a noob but i dont do DNS and i hate messing with it, im fine with everything except DNS!!! its my worse nightmare
PDC or Primary Domain Controller. This is basically where the FSMO roles are hosted (all 5 of them). This is the same for 2000, 2003/R2 and 2008/R2.
I'm guessing your server is already a GC (Global Catalog) otherwise it wouldn't be able to process logons at all. Seeing as you have one server all these roles should be on your current server. If they're not, you have two options:
- Either bring the old server back online and transfer the roles (as it says on the link)
- Seize the roles, although this should be the last step you take (only if required)
So if you follow the link I posted, start in Active Directory, right click your domain name and select 'Operations Masters'. If you click on these tabs (in turn) does the servername read your old one or your existing server?
These are three out of the five and as you can see, it's not difficult to do. From what you're saying though, the old server was simply cut off your domain which is a big no no.
- As a general rule (I've always done this), all FSMO roles should be transfered from an old to a new server.
- Then you run dcpromo and demote the old server as a DC. All other critical domain information will then be copied over.
- Then demote the server from the domain completely and it's job done.
