Have three computers both with windows 7 connected to each other with a TRENDnet gigabit switch, have a folder on computer A that is set as shared folder under the advanced sharing settings for the folder. When I copy from computer A to Computer B the process barely takes a second. When I copy from computer A to Computer C its the same story almost no time to copy.
The problem is when I copy from computer B to Computer A. It takes more than 5 minutes to copy the same file. This problem doesn't occur when copying from computer C to computer A, it is only when copying from Computer B to Computer A
The speed when doing this is around 13.2 KB/second even though all computers have gigabit cards and its a gigagbit switch.
I have tested with both computers B and C doing a transfer to computer A and computer B is going at 13.2 KB/second while computer C is going at ~50 MB/second
Computer A has kaspersky anti-virus installed but I disabled it, and all computers have microsoft security essentials installed. EDIT: tested another thing, I made a shared folder on computer B then went on computer A and copied from the shared folder on computer B to computer A and it worked perfectly fine at around ~70 MB/second.
so in the end the only problem is copying TO computer A's shared folder FROM computer B which seems strange to me and I'm guessing has something to do with the settings of the shared folder and not the network.
