I am having problems copying large files (> 4Gb) from a Windows Storage
Server to another Windows 2003 server. I am using windows explorer to copy,
It just stops part way through with an error 'specified network name is no
longer available'.

If I perform the copy the other way then it works.

Have disabled antivirus software and firewall etc, and also tried connecting
to a different switch with different cables.

Anyone experienced something like this ?
