Not sure if this is useful or helpful (reviving this issue after so long dead) but I'm having this exact problem today and it is very frustrating. I have a home network running a variety of OS, including Windows 7 x86 and Windows 10 x64. I have Drivepool 2.2.2.934 running on a server with Windows 10 x64 and I'm trying to copy video files (greater than 2Gb size) up to this box from a Windows 7 x86 client. Every time I get the 0x800705aa error (out of resources). If I test with a drive in the server that is not in the pool ie shared directly the file copy happens without difficulty.
The advice about tweaking the network auto-tuning feature was a bit cryptic but I tried various changes to no effect.
The other potentially useful information is that the server is an older machine running a collection of 500Gb, 750Gb and 1TB drives.
Any advice?
