Link to document on network

Hello everybody,

I try to open a word document by clicking on a LinkToURL or LinkToAction ui element.

The document is located on a shared drive on the network and not in the WDP application.

But I don't succeed. If I enter the link in the IE by hand it works.

Most of the time I get an InvalidURLException.

Can anybody help me or give me a hint how this can be done?

Help is highly appreciated!

Regards,

Roland
