wholder

Thank you everyone for your help I managed to fix the issue that seemed to be caused by a Invalid secure channel / Password mismatch incase people have this problem in the future Netdom to reset password very relieved man !!

i dont seem to have a local policies on my computer settings as it suggests in the article :s

i have a group policy error which says group policy failed: could not resolve the host name name resoulution on current dc or ad replication latency loads of AD errors (same error) Knowledge Consistency Checker (KCC) has destected problems: there is insuffiecient site connectivity information for the KCC to create a spanning treereplication topology or one or more directory servers with the discovery partition are unable to replicate the directory partition information. this is probably due to inaccessible directory servers And DNS errors saying DNS was unable to to open Active Directory error code 4000

none that i can see im afraid

hello, i havent tried that "have you tried reinstalling the role ?" how would i go about doing this ? and the DNS service and AD are deffinitely running. And yes ive rebooted several times, its always worth a try and i live in hope but sadly that didnt sort it

thanks for the advice though it was much appreciated, hope you can sort your problems too

windows server 2008 r2 and no ive only been here 2 days and it was working fine until about 10 this morning baptsim of fire i believe !!

As far as i know the DNS should be running intergrated zones, the error messgaes in event viewer suggest it does. They say that it is unable the DNS server is configured to obtain and use information from the directory for this zone and is unable to do load the zone without it. its very odd as i can ping the server and it a client machine knows that the DNS is on the dc01 and the domain :S thanks

thanks for the quick reply dcdiag gave this : Performing initial setup: Trying to find home server... Home Server = SVR-ARH-DC01 * Identified AD Forest. Done gathering initial info. Doing initial required tests Testing server: ARH\SVR-ARH-DC01 Starting test: Connectivity The host a3f80d71-d58c-498f-a197-0c73301dd6c8._msdcs.lcc-schools.local could not be resolved to an IP address. Check the DNS server, DHCP, server name, etc. Got error while checking LDAP and RPC connectivity. Please check your firewall settings. ......................... SVR-ARH-DC01 failed test Connectivity and sadly right clicking run as administrator didnt work i wish it had though !

Hi everyone I have a slight issue, Im 2 days into a new job and for some reason this morning the DNS has broke on the server ! When trying to run the DNS it says the server cannot be contacted, access is denied, add anyway ? This is slightly worrying as DNS is trying to connect to AD on the same machine. I have no idea why this has happend any help would be much appreciated as it's a slight issue with people not being able to get mapped drives or printers Many Thanks in advance Wayne
