Prompted for credentials

I am using Product native bootable media v3329 downloaded from My Account. I am trying to use the stand alone utility to install an image from a windows server share to an OptiPlex 380

I am able to browse to the server when it prompts me for my credentials. I enter domain\username and my password, it then displays a list of shares on the server. when I select a share it prompts me again for my credentials and this time will not accept them...it just keeps prompting me.

In my previous version of the snap deploy v3 boot media, this worked fine (it accepted my credentials and allowed me to browse and select the image...user is a domain admin). i downloaded the latest version of the boot media for the NIC drivers for the OptiPlex 380 and now I am not able to get past the credential prompt.

Thanks for any help,

Mike
