Windows 7 IPSetup not seeing 0.0.0.1

[aaronbc]

We have an issue where IPSetup will not see devices with an IP address of 0.0.0.1 This happens when a device is setup as DHCP but no DHCP server exists so the IP address stays 0.0.0.1
Windows XP works fine. What would cause this issue?
Thanks,

When it has a valid address does IP Setup under Windows 7 see it? I ask just in case you never had a need to run IPSetup until it got the invalid address. It's possible Windows 7 blocks UDP port 20034 and you'll have to adjust the firewall to open it up.

Also to avoid the problem you can always do something like

Code: Select all

if (GetDHCPAddress() != DHCP_OK) EthernetIP = AsciiToIp("192.168.1.32");

This was a bug that was in our code affecting Windows 7. If you update to the release Rel24_rc2, this should be resolved.

I just wanted to add that there is no problem with the old version of IPSetup for versions of windows besides Vista and 7. Microsoft changed how that stack works at the application level in these new versions of windows. Broadcasts were not being received by the application for some "invalid" IP addresses (0.0.0.0, 0.0.0.1 ...) but this works fine in XP.
