When I checked DHCP snap-in, I found that DHCP releases 10 ip addresses to its own server with RAS as unique id (this server is the domain server, dhcp, dns and RAS server). I was not sure what caused DHCP to release 10 ip addresses with RAS unique id. I sometimes deleted the ip address and didn't affect our operation. I observed for a while and noticed it happened every Monday and about 15:21 weekly. We have a Cisco firewall router and use the router as VPN connection. But, I know no one use VPN in our company except I. I set up WSUS and Time server on this server. If you have any ideas for this cause, I appreciate your comments.

Thank you,

Why are you running RAS?
Was it set-up to be a VPN gateway at one time? If so then it would be releasing IPs to itself to allow for this. It is not needed anymore if you are VPNing into the firewall. You should be able to remove RAS.

I am not sure that this server was set up as a VPN gateway since I didn't configure it at the beginning. However, we use the firewall for VPN and we don't need RAS, so I stopped the service. I will checK to see any dhcp release to RAS next week. So, though there is no direct VPN connection to this server, if the server is once set up as a gateway, dhcp still release ips to itself?

Yes, because it sounds as though they never stopped the RAS service or removed the configs for it to be used as a VPN gateway.

heyyou488,

Thank you, stopping the service is working.
I didn't see any IP release to RAS.
