I'm in a computer lab trying to load Vista enterprise software on a PC via a network pull. This involves booting a disk in the PC which brings up a screen to type in a shared network drive on our network. For example: \abc-prl.americas.company.comxyz_7_network_pullcontents. When the PC is connected to our Cisco 2950 12 port switch I cannot connect to the shared network drive. Connection failed. If I take a Cat5 cable and connect the PC directly into a port in the wall, I can connect. The wall jack has two ports, and the switch cable is plugged into one of them. So, what is the switch doing to deny access to the shared drive? It's plugged into the same location as the direct cable.
So, we have the same wall jack with 2 ports and different results:
PC to direct wall port - connection successful
PC via 2950 switch to wall port - connection failure
The computer lab is no different than any other room in the building other than there's just a 12 port switch for the PC's we have there.
We have this same problem with new PC's or laptops we're migrating to Vista on different floors in our building, (but in those cases the swtiches are in closets on each floor). Is this a VLAN configuration issue and we're missing something obvious?
I'm a bit of a novice and trying to help our team figure this out. Any ideas?
