I have an XP Pro machine with a folder shared to the network with full
control for everyone. Every other machine on the LAN, regardless of
Windows version or user account level, has no problem reading/writing on
this share. The share resides on an NTFS drive. There is no domain.

I have install Vista on three computers (two x86, one x64) and have had
the exact same problem on all three: the Vista machines can access the
above network share, open files on it, and write to it as expected.

The problem is with copying a file from that share to a local NTFS
volume. I can copy it to a local FAT32 volume no problem since that
strips the NTFS data from the file. I can then copy it from the FAT32
drive to the NTFS drive. Attempting to copy a file from the network
directly to the local NTFS disk results in an error message reading
"Destination Folder Access Denied: You need Permission to Perform this
Action, Try again/Cancel". I don't get a UAC elevation prompt.

However, if I create a file on the shared folder from the Vista
computer, I can copy it back to the Vista computer. Its like there's
something in the NTFS data of the files created on XP that Vista won't
copy onto its own NTFS volume.

Things I've tried with NO effect:

1) Disabled UAC

2) Logged on as an administrator

3) Logged on as a regular user

4) Enabled THE administrator and logging on as such

5) Changed where I'm copying the file to (ie. Desktop, Documents, etc)

6) Created new folder on C and verified that everyone and their brother
has full control of it before attempting to copy a file to it from the
network



The only variable I've found that has any effect on the issue is the
file system of either the network share or the local disk. If either one
is FAT32, file copying work. If both are NTFS, it fails.

Update
Dynamode 1000 and realtek RTL8169/8110 are the same ie 8169 chip.
Both Dynamode and Realtek latest drivers (although only advertised as for up
to XP) are the latest drivers and are installed on my PC. I have found
information on the internet which says Vista has drivers for and is
compatible with RTL8169.

On PC 2
When the Gigabit LAN is set to auto negotiate speed - problems with network
When the 10/100 LAN is set to auto negotiate speed - the network is OK
When the Gigabit LAN is set to 100 base full duplex - problems with network
When the 10/100 LAN is set to 100 base full duplex - the network is OK
When the Gigabit LAN is set to 100 base half duplex - THE NETWORK IS OK
When the 10/100 LAN is set to 100 base half duplex the network is OK


Conclusion the Realtek gigabit LAN drivers are no good for 1000 base and
are only good in 100 base if half duplex.

PC 1 has Onboard Intel Proset Gigabit LAN which has widely advertised its
Vista compatibility.

PC 3 has onboard dual nvidia Gigabit LAN which I have not looked into yet
