ACTIVE DIRECTORY, DHCP

we are finding  on DHCP server below

Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: mcshield.exe (1776) consumed 311754752 bytes, svchost.exe (1324) consumed 179965952 bytes, and svchost.exe (964) consumed 99065856 bytes.

these events are generated every 5 mins once it reaches its maximum state that is when server goes in to the soft hang mode

an event 7031 generated which is below,

The DHCP Client service terminated unexpectedly.  It has done this 2 time(s).  The following corrective action will be taken in 300000 milliseconds: Restart the service

we noticed the 7031 event for dhcp server service terminating at 10:01:18am and we saw the 7036 event saying dhcp server service entered running state automatically at 10:01:31AM. So in the traces also MS saw that dhcp server is serving client requests after 10:01:31AM. But as per our observation, the clients did not get IPs from dhcp server until 10:13AM when we manually restarted the service again. We are not sure why the clients were not able to get the IP address while MS clearly states In the trace that dhcp server is responding to the client queries.



any reason  as to why clients were not getting the ip's

Is your MCafee virus scanner up to date? I saw MCSHIELD running and consuming memory... I had terrible issues with McAfee when we ran it, especially if it got out of date...

I'd advise you to run wireshark on the client to check the communication and diagnose the issue. I've had a similar issue with win2k12 and win2k16, the issues were caused by pending updates, once I installed them things worked the way they were supposed. It doesn't hurt to check.
