Evening, Hopefully this should be an easy answer for someone out there. Im having a DNS issue. Somewhere along the lines i have not configured DNS settings correctly. I only spotted this recently when i had a problem with GPO's not applying, whilst my second DC was down. I have tracked the fault back to the client machine not being able to access the SYSVOL folder on DC1 using the domain.local name. \\domain.local\sysvol When i perform a NSLOOKUP on DOMAIN.LOCAL it only resolves the Second DC and not the first. I need to get DNS to resolve both DC's IP addresses again. Do i need to add a record manually? Any help would be appreciated. Gavin

Add it to the hosts file. Example: 192.168.0.100 domain.local How do you know when a politician is lying? His mouth is moving.

I agree that would work, however that is more of a work around than a fix. Plus i would have to make sure i add a line to the host file for each of the DC's otherwise any requests would always be sent to only one DC. Meaning no fault tollerance. Maybe i'll have to demote it, and then re-dcpromo it so it recreates the missing dns record.

DNS records can be manually/dynamically added to DNS. Thats the whole purpose of DNS instead of using host files. Assuming the server is also a GC and Domain controller then its records should already exist in DNS. Have you configured your DHCP scope to hand out the primary and secondary DNS? Can this other DNS server be pinged via IP address? If so have a look at its DNS and ensure it can do recursive and iterative queries. The DNS console will allow you to check if the said DNS server is capable of name resolution.

I think you would be asking for trouble if you start playing with dcpromo for a something like that. How do you know when a politician is lying? His mouth is moving.

Both servers are GC's. The clients are configured with both servers IP's for DNS resolution. Both DNS servers can correctly resolve internal and external ip adresses. My problem is that they seem to have missing records. NSLOOKUP DOMAIN.LOCAL will only resolve DC2. If i am correct it should give the ip address of all DC's within the domain. Here's an example of what i mean.(Same results regardless of DNS server used) NSLOOKUP DC1 192.168.1.200 NSLOOKUP DC2 192.169.1.201 NSLOOKUP DOMAIN.LOCAL 192.168.1.201 Where in the DNS can i manually add the record.
