Windows server 2003 crash Blue screen error.

Hello experts,

I have got a windows 2003 computer that keeps crashing every few days.
I'm always receiving a blue screen showing Stop:0x0000007F, error
I goggled that and followed some suggestion saying that its recommending to check the server memory. I did that but still no results, It’s just getting crash again
Every few days.
The big problem is that this serve is my default Domain controller, and my default dns server.
I tried to troubleshoot everything from hardware to software, including deep software diagnostic; I even searched Microsoft for any kinds of neither hot fix nor patches, but the Blue screen keep appearing again  every few days.
Any other suggestions?
Thanks’.

Shay,
 MCSA.

Can you boot to windows ? how long it takes for each reboot ? can you retrieve the memory dump file. By default, Windows Server 2003 is configured to create a memory dump ? . If no memory dump file was created before , create one Then, if the Stop error reoccurs, you will be able to extract the necessary information from it . ?

How did you test the memory?  Did you swap slots, only run one stick, etc.?

Being this is your default DC, it may be difficult to do, but i would suggest a low level memory scan with memtest 86.

Has anything changed with the system config recently?  

I agree with Adiloadilo on the memory dump.  Here is the info on that : http://support.microsoft.com/kb/307973

Post what you find.

Thank you Adiloadilo,

Yes I can reboot into Windows the server is up and running.
Each reboot its take about 4 minutes until I able to access the Sever desktop, sometimes it’s just for about 3 minutes on  "preparing network connections", and after that it’s taking me to the Server desktop. All the process taking for about up to 5 minutes, really frustrating
I attached the memory dump file for you, I will be able to check the Dump file only in Monday now its Friday. Thank you for your help please feel free to check the file,maybe you can provide me  with more information. To be able checking the Dump file by myself i need more time because i'm not famlier with the Dumpchk.exe  utility. have a good weekend.

Hi Jimmy,

I test the memory with some old software as part of our MSDN toolkit.
I opened the server and I did swap between my two memory slots, each one of them is 1 gig, total 2 gig. I left the serve case opened I’m wondering if we assuming  a cooling problem so I’m trying to be creative until Monday morning, now its Friday.
I will try to go with the Memtest86, nothing was changed recently relating to hardware.
Thank you for the useful link.
Shay.

Dear Adiloadilo,
Unfortunately, my server crashed again this morning I notice that the DMP files size has been changed. Attached is the new DMP file containing 96kb of information. Can you please diagnose the file for me? Users from the Sales called me and told me that “they are not able to access the internet”. That because my server was down and there was no other DNS server available to resolve user’s requests.
Please tell me if you can assist me with that.
 
Thank you for your help.

Shay

Dear Jimmy,

Thank you for your suggestion, I'm still working on it and I will post my resolution to you, soon. The link that you provide me with is very useful. Because this is my primary, Domain, DHCP , DNS, PRINT, FILE  server things much more complex but I’m sure that the solution will be found.
After what append to me this week I’m considering to change the network infrastructure and to add a second Domain controller that will be used as a backup DHCP and a  DNS resolver. I will start to implement that next week because I cannot allow any down time in our company. I’m thinking that 2 Domains will be served us great and I’m considering adding the second domain as a child in the existing Domain forest to allow replication, but first I need to write my plane.
Thank you,
Shay,

Mcsa.

what is iomdisk.sys  , avgmfx86.sys  ? these are the files which are causing the problemthes thes are most likely a AVG antivirus files , uninstall  AVG and reinstall again . if problem still persists then choose another antivirus solution . below is the debug info for your dumb file

Dear Adiloadilo,

Thank you for diagnosing the Dumb file for us, we do running an anti virus called Avg business edition, the latest software from AVG website.
This antivirus software protects our domain controller, includes all our servers
We have 5.
I will uninstall the software today from our Domain; I will let you know if I’m encountering the issue again. Can you please teach me how did you open the dumb file, which software or application can assist with that?
Your help appreciated.

I used windows debuging Tools to read and analyse your Minidump file :

http://www.microsoft.com/whdc/devtools/debugging/installx86.mspx#a

there are lot of articles on the internet with tutorials on how to troubleshoot bsod using debugging tools

one of the best is Microsoft Article is :

And if AVG is your enterprise A/V of choice (i.e. contract), get their support involved ASAP.  They should be able to patch this for you in relatively short period of time.

Jimmy,

I called them but AVG saying that I need to provide them with more information than the DUMP file.
Somebody needs to call me back, asking me if it’s possible connecting remotely to my server.
Thank you.
