Tool for checking domain authentication ports

I am having difficulty getting a PC connected to a domain over a site to site VPN to head office. Engineer at head office is saying all ports open. I can do an nslookup and can qery server names but am not getting password prompt just error.
Is there a tool I can use to identify what port is not open or having issues.

Is the PC you are trying to connect to the domain using a static IP?  Set it to DHCP, confirm it received an IP properly and can talk to the DCs on the other site, try adding it to the domain again.
is your vpn connetion is configured to connect to domain ?
see vpn policy if you applied
does you apply GPO that system can join domain only if they are in LAN ?

This tool PortQryUI.exe and ldp.exe allowed me to identify the issues.
