I'm having a strange problem when copying files between a Windows 7 64-bits machine ("Al") and a Windows XP machine ("Ronny"). Both are connected with 1GB network. Test 1: Logged in on "Al". Mount a disk from "Ronny" and copy a file from "Al" to "Ronny". Speed 0 bytes/second. Times out. Test 2: Logged in on "Ronny". Mount a disk from "Al" and copy a file from "Al" to "Ronny. 6 seconds to copy. Test 3: Logged in on "Al". FTP a file from "Al" to "Ronny". 10 seconds to copy. Test 4: Logged in on "Al". Mount a disk from "Ronny" and copy a file from "Ronny" to "Al". 10 seconds to copy. Can anyone help me with this problem? As tests 2, 3 and 4 goes very well, I've ruled out network problems. So why am I unable to copy files from "Al" to "Ronny" using network file copy?

You can try to disable "remote differential compressions" from the windows features. control panel > Programs and features > Turn Windows features on or off > uncheck remote differential compressions In some cases this works

Thanks for the tip. This was already off on "Al" when I did the tests. Is there a similar setting on Windows-XP? To me it seems like there must be a problem with the WinXP *receiving* the file, since pulling it goes very fast.
