Recently we are getting such DNS service error on different AD DNS servers in different places, in different times: Event Type: Error Event Source: DNS Event ID: 7502 Description: The DNS server was unable to service a client request due a shortage of available memory. Close any applications not in use or reboot the computer to free memory. At this moment DNS service stops responding to all requests. Amount of memory, consumed by DNS.exe grows up to more than 1GB. After service restart everything seems all right, and even after 24 hours memory amount keeps normal (about 75 Mb). So, I can see no logic in occurrence of described problem. No updates have been applied to DCs (DNS servers are installed on them) in last 2 or 3 months, so it is unlikely an update problem. I found several links to KB946565, but the MS07-062 bulletin was superseded twice, and there are no fixes or KB articles about memory leaks for MS09-008 (KB961063). Have you ever faced similar problems? Thank you in advance!

You can follow the steps below:1. Click Start and run "cmd", click OK.2. In the command line, type "DNSCMD /STATISTICS" and Enter.3. Go to the Memory Statistics's Tagged Allocations Section.4. Note the UDP and TCP packet allocations.

Close any applications not in use or reboot the computer to free memory. Solution : Mentioned below article from Tiger Li on technet forum is http://www.kuskaya.info/2013/07/14/excessive-virtual-memory-usage-in-dns-exe-process-after-installing-kb2647170-security-patch-on-windows-server-2003-r2-x86/ an Microsoft internal SOX which explains the design change in DNS.exe process and provides some suggestions to decrease the VM usage inside DNS.exe process. In our case the provided solution from Tiger Li did not help and Microsoft verified that KB2647170 causes a high vm usage but they will not fix the bug DNS.exe process in Windows Server 2003 R2. As a workaround Microsoft suggested either to upgrade to 2008 R2 or to schedule a batch job and restart the dns service every day to prevent to hit the 2GB VM Usage treshold.

May I know what was the actual memory usage of DNS.exe when we got this error message ? we may check it form the task manager . 5.2.3790.4957 is the latest version number of DNS.exe on windows server 2003 X86 platform based on my knowledge. So I’d say that this issue might not been caused by potential system bug here . The best suggestion we can provide it to implement workaround about shortening DNS cache lifetime to help prevent excessive memory usage.Since we have KB2647170 applied, here are some notes for reference : 1. Once DNS.EXE has allocated memory for cache, it never frees that memory which appears has high node ha
