Hi all,
I was wondering if someone could shed some light for me? The other day i accidentally selected the "always open this type of file with this program" check box in the Open with... window in the right click menu when i was playing around with a .dll file. Now i know that .dll files don't have a specific program that they open with and that .dll files are found in many different programs so it's not as easy as just going back and selecting the right program. So far it doesn't seem to be affecting the way my pc or any of my programs run, but it is annoying the hell out of me. I've searched countless times on the net and the microsoft website but i can't seem to find anything on how to reverse it. If someone could tell me how to set it back to it's original settings it would be muchly appreciated (Hope that made sense). Thanx

I have a strange problem when i try to download anything from the net be it a picture, a file or a program, it describes an RPC error?!?! or crashes and closes the window completely, anyone shed some light on this? thanks im baffled

My 3 PC's all have Vista and are all in the same workgroup. File and Print Sharing is enabled on all machines from Network Centre.

I have no firewalls.

All computers appear when I click Network, however the moment I click and try access C Drive or USB Keys or Printers on any of the computers, I get an error message. Please see the screenshot attached. What the hell am I doing wrong?

Is there something I need to enable in the Permissions area? ie: Full Access for all users/groups etc. The moment I try giving Full Access, I get prompted with a message saying, Doing this will cause access problems, bla bla bla... see screenshot...
