Windows 8 Network File Transfer Issues

I need a little help here because I've run out of ideas.

I've recently run into a problem with my windows installation. I perform a lot of file transfers over my network, and have several mapped drives over my network. My internet speeds are fine and so is every other service except for when I attempt to transfer files via the Windows file sharing protocol (samba).

The issue is that downloading from my server to my desktop over samba is broken. The transfers will "start" and occasionally show speeds of ~300KBps, but the pending time is several hours. Attempting to cancel the transfer doesn't always work and takes up to 10 minutes to disappear.

  • speed tests are fine externally
  • ftp and copying files over remote desktop works
  • uploading files locally from my server to my desktop works (but not down from the server to desktop)
  • uploading files from my desktop to my server works - getting full gigabit speeds
  • mapping a network drive on another computer & transferring works flawlessly
  • no issues with any other computers on the network
  • this happens independent of the destination drive on my computer
  • issue occurs on both of my NICs

I've already done a system restore to a few days before issues started to appear as well as upgraded my NIC's drivers. I've also uninstalled all programs since then as well as cleared any credentials associated with the server but the issue persists.

Any ideas as to what could be going on?

Bumping this because I still haven't found any solution.
 
Have you installed all Win 8 updates to date? Is the server up to date? What OS is the server? Somebody said they had issues with the search indexer causing slow copies in Win 8 but it seems to be rare, maybe you should try disabling it and see if the issue persists, that would narrow it down at least to the same issue. Try updating the motherboard drivers (intel chipset drivers, I guess) too if you haven't already.
 
Some adsl routers have problems with IGMP. They show symptoms such as you described. Try disabling IGMP routing and filtering from your router and try the transfer speeds again.

Cleared my search index in windows, that didn't help, then I disabled it, and that didn't work either.

Everything (drivers, etc) is up to date. The server I'm pulling from is running Server 2012 (which is also up to date).

IGMP is already disabled.
 
Enabling Jumbo frames seems to have fixed this. Thanks for the help ^
 
If MS had just left TCP IP alone, we wouldn't have all these stupid network issues. But you know, if its MS it has to be made proprietary......
 
Sorry to necro this thread but I'm having a similar problem and I enabled jumbo frames and did this netsh int tcp set global autotuninglevel=disabled to avail.
