Problems with Winsock and UDP access

[robdon]

Hi,

My application uses Winsock to communicate with another program I have written, and they use the UDP protcol.

The both run on the same PC, so the RemoteHost is 127.0.0.1 and using port 5400.

One of my users always gets the following errors when I try to send data...

Address is not available from the local machine

But it works fine on many other PCs.

Anyone have any ideas what this means?

I'm thinking that it might be that he has a fireware that is blocking ports?

Thanks,

Rob D.

Is the computer connected to a network of some sort? Also I would make sure that there is not the windows firewall blocking it - you can access this through the control panel. Also if you are using something else like Norton Internet security this may be causing an issue.
