Weird DNS entry

Hi everyone

I had an issue here with DNS entry. When a user vpn or internally connect into the server and get an IP address from DHCP for example they get 192.168.1.159. But when we want to sync or connect the client pc from the server using a third party software and cant get the IP address. The IP that the software recognise from the client is 192.168.40.170 instead of the DHCP range.

When i try to check the DNS entry, i found out that there is an IP 192.168.40.x record as "same as parent" entry. What is wrong with the DNS actually?

*Does IPconfig /all shows this IP on the Server?
*If you delete the entry from the DNS Server and restart the DNS Service, does it come back? If No then are you able to connect?
*Also, is this a multi-homed machine or a single NIC?
*Network Folder shows one adapter or more? Does it show any other unrecognized adapter?
* Is this DNS Server installed on a real Server or Vmware etc?
* Do you have VMware or similar software installed on DNS Server?

I have 2 NIC in my server but both IP also is not related to the entry that i found in DNS. I try remove it but it comes back after a while (maybe 1 or 2 days). No third party software installed.

Open Regedit and search for the IP that you see in the DNS Server? Chances are either the IP is tattooed into the registry or is getting through some group Policy? Any chance that someone changed it or applied this IP through GP?
