Hello Ralph,
Thank you for your post. This is George and I will be assisting you in this
post.
Sorry, I am a bit unclear about this issue. To better address this issue,
could you please help collecting some more information?
1. May I know which kind of environment these computers are in? Is it a
domain or workgroup environment?
2. Please perform the following tests, and let me know the results:
==================================
1) Try to update your network adapter driver or reinstall your network
adapter driver.
In some cases, if the network adapter driver is corrupt or is incompatible,
we may encounter some unexpected connection problems. Therefore, please
check the network adapter manufacturer's website or contact them directly
to whether an updated version of device driver is available. Please ensure
that we should use drivers for x64 operating systems.
2) Disable the firewall on both the client and the server, and then try to
copy the same file. Is it working well? Firewall might cause this kind of
network sharing issue.
3) You can create or put some small files in this folder, which is much
smaller than 50M. Try again. Does the copying work well this time?
4) Can you access these Windows Vista computers from the Windows Server
2003 R2 one? Can you access these Windows Vista from your previous Windows
Server 2003? Can you access Windows Server 2003 R2 from Windows Vista by
UNC (by clicking Start-> Run -> type "\\server\shared folder")?
Please let me know these results for further resolving. If anything is
unclear, please feel free to let me know.
I look forward to your reply. Thank you!
Sincerely,
George Yin
