Hi,

Thanks for the links - better than the ones I found.
Haven't read them all yet but the first link seems to suggest a simple solution:
If running [notepad “FileName:Zone.Identifier"] allows you to change and save the ZoneId setting then maybe I can just do the same thing by opening it in .NET ?

I'll try it in the morning........
Best,
Viv
