Windows 2008 Server - cannot copy files from server to another machine; reverse works ok

 

Hi!

 

My Windows 2008 Server started acting up on me all of a sudden.

 

Every time I try to copy a larger file from it to a network share on another

machine, it freezes, reporting that the local file I am trying to copy

cannot be found ("Item Not Found" error dialog", or that there is a network

error accessing the local (!)file. Sometimes the copy works a bit at the

beginning, then the speed crumbles to < 10KB/sec, and the errors pop up.

All machines are in a Windows 2003 AD, the 2008 box is a workstation, not a

dc server.

 

I managed to disable all advanced tcp features (RSS, Chimney offload,

receive windows tuning, congestion control), and now I can at least transfer

files to a Windows 2003 server (slow; 4MB/sec). Transfering to vista x64

(also with modified txp features) still doesn't work.

 

What's funny is that going in the oposite direction - putting the files onto

the windows 2008 server box - works without a hitch. From the Vista box it

goes with cca. 11 MB/sec.

 

Any hints on how to fix this? The 2008 Server is my primary development

workstation and this is a *major* pain.

 

Thanks & Best Regards,

 

Sigmund

When you are doing large file copies using anything with Buffered I/O,

you can actually exhaust your resources, much less have a very slow

copy. Buffered I/O will consume Paged Pool (1 KB of paged pool is

required for each megabyte MB of file size that is opened for buffered

I/O). So the bigger your File Copy, the more Paged Pool you will

consume and eventually your copy might fail if your resource runs out

before your copy Finishes.

 

Thats why its good to use tools such as ESEUTIL (if you have Wxchange

Server at your site) that don't utilize Windows APIs CopyFile or

CopyFileEx for large file copies. I believe GNU Wget

(http://www.gnu.org/software/wget/index.html#downloading), Teracopy

(http://www.codesector.com/teracopy.php) and SecureCopy

(http://www.scriptlogic.com/products/securecopy/) also work well.
