Large Files are locking up Windows 7 32 bit and 64 bit
I am a tech and have done over 30 clean installs and cant figure out what the heck is going on with large as in 1gig or more file transfers hanging up. All clean installs with tests done immediately after activation and updates. This is a MS problem. I have tried all the various fixes and find that the C drive seems to handle network files best. In multidrive situations turning off the Remote Differential Compression also seems to help. Please get a hot fix as this is on multiple machines and very easy to duplicate. I would say it would be a rare install not to lock from a C drive to a D drive when file sizes are more then 2 gigs. You guys are running out of time. I am a consultant and I'm ready to get sick over a great operating system that's worthless for large video files.

Did you try this one Apparently you need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly. Set the following registry key to ‘1′: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache and set the following registry key to ‘3′: HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size After making these changes and restarting, I haven’t seen this issue arise again http://alan.lamielle.net/2009/09/03/windows-7-nonpaged-pool-srv-error-2017

Just to clarify, the LargeSystemCache key has no effect on Windows 7. It was only used on 32-bit, pre-Vista versions of Windows. So if the above steps make any difference, it must be because of the other setting.

Just to clarify, the LargeSystemCache key has no effect on Windows 7. It was only used on 32-bit, pre-Vista versions of Windows. So if the above steps make any difference, it must be because of the other setting. Two questions. !. If LargeSystemCache is not used on Windows 7 and on 64-bit computers, why is the value in the registry? And 2, more importantly, do you know of any other solution then to the 2017 issue? I have Win7 64-bit with 12GB RAM, dual quad-core Xeons. I should not be seeing memory limits copying a few files to my Win 7 home server. Thanks, Dale

The LargeSystemCache value was left in the registry (even though it is no longer used) for compatibility reasons.File server is not my area, so I don't know what the other registry key mentioned above (LanmanServer\Parameters\Size) does. I see it mentioned in a few places on technet.microsoft.com so it might be worth trying but I'm not in a position to make any statements regarding its applicability to this particular problem.
