Hi Rob,
Deploy Anywhere will check the missing drivers for the Operating System and is used after image restore.In your case the drivers might be missing for the WINPE environment.There are two causes for 10030 error,
1. Nic drivers missing for WINPE
2. AV/Firewall on Ghost Server is preventing the communication.
Boot to WINPE and do an IPCONFIG under the command prompt.If you get plain Windows IP configuration,drivers are missing for WINPE.Add Vista 32 drivers as the WINPE version in GSS is WINPE 2.0(Based on Vista code& 32 bit in this case).
If there is valid IP address ,ping the server and proceed accordingly.
EDIT :
I happened to miss the NIC model .Intel I217 ? Well there are no Vista drivers for this particular model(even Intel did not release Vista drivers).So,the only option is to use WINPE 3.0 boot media by following the article mentioned below,
