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.
