I have a computer I need to put onto a workgroup which is currently opperational with 13 other devises and computers. When I try and access the workgroup it tells me that I do not have permissions or have limited or no connectivety but, I am able to access the internet with the same computer. This computer can ping all of the other computers as well. The plan for this computer is to set it up with a shared external HD which will be accessed by the rest of the 13 computers. That will be its sole purpose. Can somebody please help me with this issue.:confused:
