Crucial Domain Problem

Guys!
Everything was working fine when i came to office today and suddenly i came to know that the Group policy is not working properly and there was some other error messages in even log. So upon checking few settings and updating the DNS settings i made the worst mistake and restarted the server resulting now everything is messed up.

I can't see network conenction and upon click refresh in network connection window i get error message "the folder is unable to retrieve the list of network adapters on your machine, please make sure that the network connections service is enabled and running"

when i checked the services almost everything is in not running state and upon running the services like netlogon i get the error message "Error 1068 the dependency service or group failed to start"

I am not been able to see the properties of any service as well.

This machine is PDC, running DNS only.

I am in a mess and need help, if you require further information do let me know.

Dead network card?

Nope both NIC working fine

booted in safe mode, tried to restore last good know configuration but nothing works same problem in every mode. Can;t open properties, DNS giving error, no AD :(

I made a changing in windows firewall: Allow remote administration exception option and enabled in using mmc, now i want to revert and just to see if that was the issue. But again i can't open the properties of this option.

Well I found this link that has a couple of steps that might help, not sure thoug has no one has posted a follow up as to weather it worked or not... its worth a shot though...

Can you ping any internal machines???

Can you ping the internet??

Well know i am able to see things but still one issue remaining, when i try to ping myserver from the same machine it resolve OLD IP address on the other hand when client ping myserver they get the orignal IP of the server. I run nslookup and its working fine, i think somehow the server IP got updated and still the record is not update in DNS.

I have manually update the records but no use.

Regarding not been able to access anything was the rpc logging error, this was resolved by changing the login account detail through registry: -

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\RpcSs\
Object name key is logon account for the service.
Changed it to original value "NT AUTHORITY\NetworkService

But still that IP resolution issue is not resolved and still server resolving to old IP.

ipconfig /flushdns

Your Time is off
set a reliable time sorce then

W32TM /resync /rediscover

all done

@MLF
Did that hundred of times but no use.

@dinowuff
Getting error "The computer did not resync because no time data is available"

There is a DNS error in the event log Event id 6702.

"DNS server has updated its own host (A) records. In order to ensure that its DS-integrated peer DNS servers are able to replicate with this server, an attempt was made to update them with the new records through dynamic update. An error was encountered during this update, the record data is the error code."

Also when i try to access the GP for any OU i get attached error messages.

So can you ping 127.0.0.1???

Sounds like you have a hardware connection issue...either NIC, cable, switch.

@MLF
Yes i can ping my loopback and i am doubtful its hardware issue.

When i run dcdiag, i get error: -

Server MYSERVER resolved to this IP address OLDIP,
but the address couldn't be reached(pinged), so check the network.
The error returned was: Error due to lack of resources.
This error more often means that the targeted server is
shutdown or disconnected from the network
Done gathering initial info.

I have removed the DNS re-install it but issued remains there, when i run arp -a i found the old ip with 00 as mac address and invalid as type, removed the cached and now i am not seeing that IP but still DC resolving its name to OLDIP.

I belive some record in AD or my router (acting as DHCP) is not refreshed and server gettin updates from there.
Is there a way i can check the current DC record in AD?

Ok...so you can ping your self...means the NIC is working...but doesnt you are actually connected to anything
can you ping anything else??

Did someone add the ip address of that server to the hosts file? check in %windir%\system32\drivers\etc\hosts for a static entry in the host file.

nslookup would show the correct address because you are asking the dns server for it's host record of the particular machine. resolution is a bit different. it will look to your hosts and lmhosts file before it uses dns

I suffered through this ordeal some time ago. Sad part? I completely forgot what caused my issue and how I fixed it. In any event, I vistited some sites I had boomarked and ran across this:

Quote:

---

The mandatory Connectivity test is executed on every DCdiag test run. This test verifies the most important functionalities of a domain controller: whether all DNS resource records are registered on the preferred DNS server, and whether DCs are pingable and have LDAP/RPC accessibility. For example, using /a or /e parameters, you can quickly find all DCs that are not responsible

This was an elaboration of the DCDIAG message you received.

They then suggested running netdiag /test:DNS

This all came from here

It's killing me because as I re-read this stuff, I vaguely remember cursing alot and spending late nights staring at DCDIAG results.
