I found in my domain controller DNS.exe is utilizing more CPU resource (UP to 100%) on the server, I hope that DNS.exe service is not releasing the memory and the CPU usage come back to normal after restarting the DNS server service. Also, while launching NSLOOKUP on the server we are getting the "request time out" Could you please have look at in this issue.
if the articles posted from Syed doesn't help to resolve the issue please post the OS version used, including SP/patch level. Additional check the event viewer for errors and post them here complete if exist.Best regards
