VCSA not joining AD..

Hi,

This ia workstation deployment.

I have been trying to join VCSA to AD using this steps : Join or Leave an Active Directory Domain have not been successful, unsure where the mistake is.

After VCSA keep on trying I receive javasockettimeout error in VCSA, after which when I restart I can see VCSA joined in the computer section in AD, but in the VCSA window it says join domain.

Any thing I might be missing.

I'm joining using the following settings.

Domain - vi.lab

Username - Administrator@vi.lab

Thank You
