Are you Using createObject("MSWinsock.Winsock.1") ? If so, it will not work at run time because it needs a design time license. To work around it create a form and drop the winsock control into it. Then:

loForm = CreateObject("YourFormWithTheWinsockControl")
? loForm.oWinsock.LocalIP
.....
loForm.Release()
