Title: Win 98

These rogue ip address are probably APIPA allocated IP addresses. When a 98/2000 machine can't connect to a DHCP server but is set up to use DHCP an IP address will be allocated from the range 169.254.0.0 and a subnet mask of 255.255.0.0.

 

This is allocated via a local service called APIPA (Automatic IP addressing)

I've had a problem where a laptop running Windows 98 was picking up rogue IP addresses. There was nothhing wrong with 98 or the config. In the end it turned out to be the NIC driver. Got the updated driver from the web and that fixed the problem.

I got a good one for you guys. I have a NT4 DC server running DHCP/DNS/WINS. I am on a class B private subnet using the 10.52.x.x address range. I have a 98 machine that everytime it tries to renew its lease at the half-way point, it changes the subnet mask from a class B 255.255.0.0 to a class A 255.0.0.0. Once that happens, of course all it can do is access local machines and will not be able to get passed through my router for internet and corporate access. I have done everything short of reloading the system, which will get upgraded to 2000 soon. But I am curious if any of you guys have bumped into this, since it is only one machine? Please help!

Thank You,
