I have two PC's both with XP pro and they are connected together by means of an ethernet network. If I make a share on PC1 and then I try to copy from the other PC (PC2) to this share the copy starts but after one minute the copy stops and I get an error message telling me that the other computername cannot be found. If I check on that computer the file is there but the size is not correct. When I copy a file from this share on PC1 to the PC2 everything works fine. That's the only problem I have with my network, all other things work fine.
