File transfer between Windows 7 and 2008R2 hangs

Fri, May 13, 2011

Immediately after starting a file transfer, but generally after some small amount of data has been transferred, the file transfer seems to die. I experienced this on a Windows 7 Client and 2008R2 server while transferring a series of large files.

I attempted to stop active AV checking temporarily, which had no effect. I re-enabled AV and tried to use PowerShell to copy the file instead – no doubt still using the same underlying protocols. To no avail.

Next, I tried disabling SMB 2 on both the client and the server. This resolved the issue.

In order to disable SMB 2, and a DWORD of Smb2 with a value of 0 to the “HKLM\System\CurrentControlSet\Services\LanmanServer\Parameter” key.
