Cannot access Server 1 from Domain A to Server 2 Domain B on a AT&T MPLS network via hostname but can access the server by IP Address

Good afternoon-

I am having difficulties adding users from Domain A to Domain B shares under security tab of the specific share. Although I'm able to change the location of the user to the domain they belong but when I type in the user name under sharing and security of the particular share I'm granting them access to, I receive a message stating that the name cannot be found.

I even begin trouble-shooting dns which has the forwarded lookup zone for Domain B. I also setup a 2-way domain trust and enabled WINS.

The funny thing is I can ping the ip address of the server on Domain B and even ping the FQDN name, but cannot ping the hostname of the server on Domain B.

Any help with this matter would be greatly appreciate.

Best,

RB

Is there a trust between the domains?

Yes a 2-way trust that I validated but it did ask for a password reset on the one server from Domain A

You would not be able to ping the hostname on DomainB.  By default you can only ping hostnames that exist in your local domain.  It makes sense that you can only ping by IP and FQDN outside of your local domain.

Are you able to add users from DomainB into groups in DomainA?

Overall, I am trying to add a user from domain B to a share on Domain A when I access the share and right-click on it, go to sharing and security, from the sharing tab I click add, I change the location option to domain A which shows up, and input the username from domain b and the system states the name not found.

You will not be able to add users from DomainB using DomainA as the search location.

You will need to specify domainb\username or browse with Domain B as the search location.

You might be misunderstanding me.....I am using domain B as the search location while on Domain A because I have the option....So I did change the search location to the correct domain (Domain B) and trying to add a user from that domain B to the share on Domain A but the system is telling me the name not found

If you click on the Advanced button in the lower left and click find now, does it return any users?

No users at all....I tried that as well. That's why I think I'm having either a dns issue or trust issue even though the domain B is showing up in the search location

Do you have any kind of firewalling enabled on the domain controllers?

If you can ping by FQDN then DNS is fine.  There might be an issue with the trust.  Did you test from both directions?

Acutally, What about AD sites and services. I'm going to add the domain B subnet on domain A. I'm going to also try and validate the trust again to see if there's an issue with that. I'll let you know. Thanks

I looked in event viewer and saw event id: 1030 and 1006 which indicated a userenv and error, and also Group policy processing aborted. I then did some research on these 2 events and found out that I had a user (the same user indicated inside the events) disconnected within Terminal Server Manager for a long period of time. Especially since she was no longer with the company. Anyhow, I logged that particular user off, did a gpupdate /force and went to the share I was trying to add the user from another domain and was successfully able to add.

Thanks for your help.

mattvmotas answered the overall question about pinging the hostnames from cross-domains, but what I was really after is why I couldn't add a user from a trusted domain I had in place all along to a share on my local domain.

mattvmotas thanks for your help!
