DNS Server on W2K - The exception generated was c0000017 at address 77F9C170 (RtlIsValidIndexHandle)


  • Hi - hope someone can help. Since last Sunday, our DNS server has been stopping with an event id of 7031 - The DNS Server service terminated unexpectedly.  It has done this 1 time(s).  

    DNS is causing a DRWatson error of 

    The application, dns.exe, generated an application error The error occurred on 06/29/2013 @ 10:02:05.002 The exception generated was c0000017 at address 77F9C170 (RtlIsValidIndexHandle) 

    The machine is a primary domain controller running Windows Server 2000 service pack 4. We've never had problems with this machine before.

    I cannot find anything really relevant on search engines regarding the DrWatson.

    Does anyone know of a cause or fix for this?

  • Hello,

    having no problems until now, then you are really lucky. Get RID of this old NOT supported OS version from a DC.

    Is that server rebooted and running, what have you done until now? Please provide more information about the current status of the server.

    Best regards

  • Hi...

    server has been rebooted, chkdsk is fine, no virus or trojan. Appears to happen every 12 hours, so I suspect it might be something with one of the secondary domains.

    What I'm really interested in is the RtlIsValidIndexHandle error and what that might point to.

    I'm a firm believer in "if it ain't broke, don't fix it" which is one of the many reasons I haven't attempted to upgrade the server. The whole setup is rather complex, as most things are, and everything hangs on a thread.
