There is a workaround for this which is in the link below.
What worked however is this:
reg add HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters /v Size /t REG_DWORD /d 3 /f sc stop LanmanServer sc start LanmanServer
Will have to research and update link with whatever is being done, but this worked for mounting my Google driver server windows 7 system.
Windows Xp so far has not shown the problem. Other options have been necessary too, this is just the latest.
Occured on a Cubox debian Wheezy system on 3/27/2017 for me.
