Re: DNS Server service stopped without any reason - System Admin Discussion Boards

The clients default gateway is the IP or the interal NIC on the server right?

a ping isn't really that good a test either, especially pinging external IPs.

Haven't done this with Windows, but having setup PIXs and ASAs I'm not sure you want to enable NAT on the private interface. You want to NAT traffic from your internal LAN out through the public interface, but I'm not sure if this would be accomplished by enabling NAT on the private interface in Windows or not.

Just out of curiosity if you type: "route print" at the command line, does it show 0.0.0.0 0.0.0.0 to have the gateway for external traffic?

Any reason your not just using a Linksys or similar box to perform this?

Hi,
I changed the internal nic to static 192.168.10.3, with DHPC range 192.168.10.x.
Public NIC is still the same, only now the DNS shows to the new internal address 192.168.10.3.

Firewall is off on private interface.
Clients can ping outside interface successfully.
No static routes are defined(yet ?)
No RIP enabled (yet)
All Firewalling is of.
No filters are defined.

DHCP Router(Option3) set to 192.168.10.3
DHCP DNS Server(Option6) set to 192.168.10.3

DNS Interfaces set to 'ALL'
DNS Forwarders set to ISP DNS1 and DNS2

Clients are unable to ping ISP DNS1 and DNS2, although server can.

Should we have a look at RIP2 then and what do the settings need to be.

Hi, I have a problem with my windows server 2003 Sp1 DNS service. The problem is the DNS service on windows usually stop whether I changed its setting to Automatic Start for DNS Server service. As network administrator, I didn't change any setting relating to DNS service after I have configure it correctly.

From here, I would like to know whether some of you experience with any virus that could stop DNS from running? When its stop, my whole organization could not access to an internet for a while. So I have to enable it every time to solve the problem. My concern is sometime I need to travel away from my office and this problem occure, so there would be nobody could solve this problem.

Thank in advance

You did read this one[^]
in the daily CP newsletter, did you?

I hope your problem is something else tho.

Thank you very much for your reply

I would update to Service Pack 2 first of all, there is always the chance that will solve the problem, plus probably better of at SP 2 anyway if at all possible.

Are there any errors in the event logs related to the DNS service? Is all DNS name resolution on the network failing or just Internet related queries?

I probably wouldn't point to a virus for this problem, although its tough to say from your description. Up to date virus signatures and a full scan are never a bad idea though.

You may want to try reinstalling DNS if updating to SP 2 doesn't help. (If you only have one DNS server and you're using Active Directory you might want to look for a MS document on how they say to do this, if there is one.)

Thank you very much for your comment. I have run windows update on the server and found that its recommend to update to windows 2003 sp2. Currently this server is acting as domain controller and file server which share a document to all user in the organization. As I have discussed with my team, I not sure whether if I apply sp2, whether the the server could running properly or not (may be it could cause some problem with any device driver, or strict any security seeting) which could cause a trouble for user to access the resource on the server. If you have any experience with sp2 on windows 2003, please let me know whether it have any problem or not after you apply it.

When I found that the DNS server service is stopped, around 70% of my client couldn't access to an internet. But each client I also configure with an alternative ISP DNS. I also have some problem with my router too which could make me difficult to find the problem. After I turn off the router for 10 mintue and restart the DNS services, every body could access the internet again. I have check an event viewer to find the cause of the problem but I didn't found any entry that could cause DNS server service to stop. But I found the below entry that is related to the DNS server service:

The DNS Server and Domain Controller is set in the same machine. Please let me know if you have any idea. Thank in advance.

Personally I have not run into any problems with SP2. I manage quite a few Windows 2003 Servers and I have not run into a problem. If you're worried about driver compatibility you can research that with the vendor that the server came from, or if a custom built you can look into individual components.

I personally would never configure a domain controller to have DNS point to anything but itself or another internal DNS server. I would not point a DC to an external DNS server. Pointing clients to another DNS server is probably alright, although if you configure DNS to use forwarders for external queries it isn't really necessary.

You might not be doing this, you said only clients, so that might not be relevant.

Can you access the internet when the DNS Server Service is stopped? IE ... telnet to port 25 or 80 of some external server that you reference by IP address, thus bypassing DNS resolution all together?

As a temporary solution, to allow you to leave your office, you could set the service to restart automatically.
In the services console, doubleclick the dns-service (or rightclick and select Properties). In the properties window select the recovery tab and select your options on failure.

You naturally need to address the issue why the service fails. But to help you with that we need more data, such as relevant entries in the event log.
When you have fixed the problem. don't leave the setting on automatic restart. It might prevent you from finding out that you're having a problem. Atleast if you like me read the eventlog irregularily.

Thank you very much for your comment. That is one solution that could help me to temporary solve it.

That was my biggest challenge. I have checked in the event viewer and there is no entry that show me the reason why DNS server service is stopped. But I found the following error related to DNS server service that could give you some idea:

Please let me know if you have any solution with the above error escription. Thank in advance!!!

If you get these eventlog entries when the server is started, then it's normal, the dns service has just started before the AD.

Try to uninstall and reinstall the DNS role on the server. That will fix any eventual file and registry errors regarding the DNS, and it's done in ten minutes (no restart) so it won't really affect the users.

About the servicepack: I always servicepack my computers a couple of weeks after the packs are released. They fix more problems than they create. And if there are any serious errors in them, it would create enough articles about it that it would raise above the normal internet noise.
But of course, as always you need a proper backup before you do it!

Hi all,

I have a pc with pre-install winXP. Now i would like to install win2000 in it. Everytime after it inspecting my system, then will prompt me "inaccessible_boot_device" message. I know it could be cause by the hard disk controller (i am using SATA hardisk). May i know how to solve this problem?

thanks in advance

Hi all,

I have found a solution which is said that need to extract the Intel(R) 82801GR/GH SATA AHCI Controller Windows driver to a floppy disk.After that press F6 to add the SCSI at the begining step.Last continue the installation as normal. I had follow the tips and do it,but it still prompt me the error message above.Below is the link i follow to fix the problem:

Hello there.

I have setup triggers on MSMQ private queues

I wanted to trace MSMQ Trigger activities for the whole day

I tried using trigmon.exe but it shows trace log from the time trigmon.exe is opened

But I want to have trace log for the whole day

One option is to let the trigmon.exe remain open

Is there any other option?

Is there some place where MSMQ Triggers activity is being saved?

Is there a way of knowing (through an application's code)if a process is still running or it hanged?
I'm trying to design a watchdog that has to monitor some processes. Except for killing/starting them, i have no other access to these processes.

Thanks

Can you see them on the Task Manager and did you test ProcessMonitor?

I can, the problem is that those processes might hang and i need to know when this happens and restart them from a watchdog.

If you can write code for the critical process, have it send a message to your watchdog on a regular basis. If the watchdog misses two or three messages, it kills and restarts the process. If you do not have access to the code, you will have to look for something the process does on a regular basis and maybe key off that. What does it do that makes it critical? That may help you find something to monitor. Can you write code to check the program counter? Where is the PC when the process hangs. What about I/O count?

Thanks for your time

Thank you. Actually this answers my question. I was wondering if there was some kind of an OS/kernel way of testing if a project is still active or not. I've done some reading and didn't find any reference to what i needed. The options you've posted above gave me the answer i was looking for.

Thanks,

Hi everyone,
I have three OS's on my system Xp,server 2003 Pack2 and Vista now I want to delete and reinstall these Os's of my system,my drivers are NTFS.When I was trying to boot my system with driver A: I cant format any drive and it shows me c: or d: are not exist
how can I do it?

Boot your system from CDROM or DVDROM.

Hi,

Please know that when we boot the system with Drive A: it does not recognize the NTFS partitions of the HardDrive. The better option is Boot the system with CDROM or DVDROM.

Hope this helps Smile | :)

Hi,
I was wondering if it is possible to simulate a file in windows? i.e. The file doesn't actually exist in the file system but i can open it in any application and my executable (or dll/fsd) provides run time data to that application for that file?

e.g.
C:\Windows\notepad non-existent-file.txt

The above command will open notepad and the notepad will try to access the file 'non-existent-file.txt' in the current directory. This file as the name implies doesn't actually exist and i want the OS to provide my application's dynamically provided data?

What i am really interested is the right direction? Is it possible? and do i need to write a File System Driver or some hooking is available in Windows?

Thanks in advance.

I believe it could be possible.. One way you could do it would be to API hook Kernel32, where the OpenFile function is stored.. Most files use this function to open a file so you could potentially get the file parameter passed to it and then do whatever you want with it then pass your newly created handle back to the calling process.

Conveniently there is an article on API hooking on The Code Project here.

Hope this helps,
