Experienced the same problem discussed in this topic:
https://www-secure.symantec.com/connect/forums/remote-install-windows-7-pc-fails-access-denied
But the difference is that it happens on a Windows Server 2003.
After logging in the authorized credentials for the deployment, and verifying the IP, it stops during the copy and displays this message:
Windows firewall is off (when i do Start -> Run -> Firewall.cpl, it says that to turn Windows Firewall, you need to turn ICS; which i assume it currently off).
I checked also the ports and they are open.
I checked the ADMIN$ and C$ shares and found out that they are disabled, so I enabled them right away,
On other machines, deployment is ok.
Any other ideas why this happened?
Your suggestions could help me.
