Specs: Windows XP
My Network is running Windows Server 2003 and with more than 150 Users. But last week, I notice that a program is changing my DHCP server IP Address scope. Example, my internal address scope is as follows:
IP Address: 10.192.0.0
Subnet Mask: 255.255.0.0
Gateway: 10.192.0.4
But surprisingly, last week, I keep seeing systems having IP address like this :-
IP Address: 10.192.193.30
Subnet Mask: 255.255.0.0
Gateway: 10.192.0.4 and so on.
Immediately I noticed this, I scanned my DHCP Server with NOD32 Smart Security and McAfee antivirus solutions and they found no threat. I use malwarebytes and it discovered nothing but the problem still remains. How do I resolve this problem?
The only way I connect some system now to access Internet is manual configuration.
Is formatting and restoring the DHCP Server the only way out of this mess? Please, I need your help.

The address scope that you give covers addresses in the range 10.192.0.1 - 10.192.255.254. So what's the problem?

Perhaps you meant to use a 255.255.255.0 subnet mask which would result in
10.192.0.1 - 10.192.0.254

Should be a simple matter of changing the subnet mask in dhcp as well as all statically assigned devices.

Your ip assignments /dhcp has nothing to do with a machine not getting internet access. You have a valid gateway.

Answers are only as good as the information you provide.
