Les,
Brilliant. Yes, the Windows 2003 Server contains;
Symantec Antivirus
Version: 10.1.5.5000
Scan Engine: 81.3.0.13
Realtime Protection: Enabled
Exclusions: None
Should I exclude the drive (S:\) on the Windows box in the AV; have you ran into this and did doing this solve it for you?
Thanks,
LK

Is there a virus scanner on the windows box? It might be taking too long to
scan the large file you are trying to write and causing the timeout.
