No network acces to server

Posted on 2012-09-11
Last Modified: 2012-09-12
I've got a server running windows server 2003 and two PCs running XP all connected to a Linksys router.
I changed broadband provider and re-cofigured the TCP/IP settings.
All 3 machines have internet access and the two XP PCs can see each other on the network.
The server can't see anything on the network or visa versa (internet is okay)

When I was entering the settings into the server I got this warning ....
Default gateway is not on the same network that is defined by the IP address & subnet mask

There are the settings .....

IP .... (.102 on the other XP Pc & .150 on the server)

I have no access to the router .... it's locked. The broadband company can access it wirelessly.

I'm stuck ... Please help

    Try putting your server address at 125

    With a mask of 128 your last address is 126

    by:jhheider should be - So, I assume assigning the .150 is where you got the error. That address is in (the next subnet of that class C). Moving it to any IP .126 or below should resolve the issue. I'm frankly shocked it has internet access, since that shouldn't be working, but that's certainly why it can't see the devices, since you have them on two different networks.

    Thanks for your help. I'd appreciate it, if you could point me to some reference material explaining the subnet / ip range issue.

    I used to have the server at and the subnet mask at

    Subnet mask defines network. It gets much easier if you think about bit-masking, but should give you all the information you need to decide if you need more information.

    There are also a number of subnet calculators online that can help.  Do a search for subnet calculator and choose one that you are comfortable with.

    I personally like:
