Intranet File Copy Issue - Win 7
Hello all,
I am having an issue copying files greater than 1mb across out network, however, I can download a file of any size off the internet.
Here's the situation:
I have a Windows 7 32 bit (have also tried 64) machine that is trying to copy a 16mb file from another Windows 7 32 bit computer, on our network, but at another physical location. The files is NOT being copied through a server. I can copy a 550kb file no issues from this location. Any file under 1mb will copy okay, anything over 1mb will not. It will come up and say it has lost connection to the network. I have covered the majority of basic and advanced troubleshooting (that I can think of).
This would seemingly point towards hardware being the issue, however, I have tried a total of 5 NICs.
Two of the mainboards being in totally different computers, Dell RMAd the first one because of this issue, both are base Win 7 32(or)64 bit Dell Optiplex 7010s.
I have tried four different mainboards in total, all the same.
I have tried a PCI NIC in each of these boards, same thing.
I have tried same/different network ports, same/different cables, VPNs, different remote locations.
I have tried a known working Win 7 64 HDD from an identical Optiplex 7010 in the original machine, and the replacement, network copy still does not work.
I have taken the HDD from the original machine, and the replacement machine both and put them in an identical Optiplex 7010 I have and they copy just fine.
I have tried it on numerous active directory profiles, through safe mode w/ networking, etc.
I've updated/flashed BIOS, rolled back and updated NIC drivers, tried 32 bit and 64 bit versions. I've tried the duplex speed settings, jumbo packets, etc.
I am a bit confused here guys.. not sure what the issue could be if it is not hardware.
Any help or advice on this would be GREATLY appreciated.
Thank you all for your time,
Cody
