Error Message:

Invalid IP or subnet mask address.

Explanation:

In the TCP/IP Configuration dialog box, you specified the IP address or the subnet mask in an incorrect format. IP and subnet mask addresses are entered in dotted decimal notation, which depicts each octet as a decimal value separated with a period. An IP address looks like this: 102.54.94.97

User Action:

To re-enter the IP address or subnet mask in the correct format, double-click Network under Control Panel. If the formatting is correct, then a wrong value has been entered for either the IP address or the subnet mask address. Ask your network administrator for the correct addresses.
