Unable to Map Drive With Resco Explorer

[Hagow]

Hi all, I tried doing a search but with no luck.

Here's the problem:

I use to use Rogers cable internet, now I switched to 3Web DSL and is currently using a GigaFast router because my Linksys router broke.

I was always able to access my home PC through my x50v with Resco explorer's "Map Drive" function but ever since the switch I can no longer do this. When I try it, it gives me this message "Cannot map network path. Network resource cannot be found or you do not have a permission to access the network. Contact your network administrator." WFT I don't understand it!

Can it be certains settings I need to enable with my router?

Oh, yes I use to have a static IP not I am on a Dynamic IP does this make a differnce?

This is all the info I have and I really hope you guys/gals can help me.
Thanks!
