Hello
since recently I got a weird problem. Let me explain my setup first. I use a Win2k server that is connected to the company LAN and to a lab-setup LAN. The server is DHCP client on the company LAN and NAT-router/DHCP server on lab-side. The lab network is 192.168.0.0/24, gateway is the server, with fixed IP address 192.168.0.1
That’s all concerning the setup which works fine, normally.
Now I get this strange result: suddenly it seems that the subnetmask of the lab side is ignored (or is set at 0.0.0.0): every IP address you try to reach, is searched for in the lab-LAN: the server even makes ARP requests to any webserver on the net you try! When I take a look at the settings, they seem OK. Just changing the settings and putting them back as they were, solves the problem, for about half an hour.
I think this could be a virus, but I cannot find a thing with an updated McAfee viruscan.
Any ideas?
with kind regards
