Hi All,
I'm having an issue when copying files from a Windows network share. If the file is above 5MB it will start copying and then after a minute or two I will get an error such as:
Interrupted Action
An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem.
Error 0x8007003B: An unexpected network error occurred.
The network share is in a different office and is accessible over a point-to-point VPN, so the connection is not that fast.
But before everyone tells me to start diagnosing the router and or VPN please take note of the following:
- My colleague who is running Windows 7 can copy files from the network share fine
- If I run a Windows 7 VM on my Windows 8.1 laptop I can copy the files across fine
I also know it isn't an issue with this particular file share. I set up a little lab, where I had one VM which had a shared folder and 2 other client VMs one running Windows 7 and one running Windows 8.1. I limited the bandwidth to the two client VMs to a similar speed we see across our VPN. The result was that the Windows 8.1 failed with the same error above, whereas the Windows 7 copied fine.
There is also a noticeable difference visually when copying using Windows 8.1 and Windows 7:
- Windows 7 - The progress bar progresses smoothly giving the current speed and estimated time remaining
- Windows 8.1 - The progress bar progresses in a jumpy fashion. E.g. it shows no progress, then after a minute it jumps and shows 16% progress, then shows no further progress, then jumps by another 18%. There is no estimated time remaining.
I ran Wireshark to investigate what was going on at the network layer. I see the following behaviour:
- Windows 8.1 - The file is copying fine then all of a sudden there are a lot of TCP dupack packets. After which the Windows 8.1 client sends a RST packet and then the error pops up.
- Windows 7 - The file is copying fine then you also see a load of TCP dupack packets, however no error is displayed and it continues copying fine.
I'd appreciate any help with this I'm hoping there are some settings I can change to make Windows 8.1 behave more like Windows 7!
