Cannot access file shares between AD forests - one way fault

Hi All,

I have a weird fault with file shares between two seperate AD Forests.

Forest A can access Forest B file shares without issuse, prompts for credentials for \\fileserver.domainb.local and allows access once authenticated.

Forest B cannot access any file share resource on Forest A, I am not prompted for credentials or anything. No acction occurs when accessing resource \\fileserver.domaina.local

FQDN resolves between each side without fualt. And two trust authentication is responding for other services such as exchange as well. I cannot get file share to respond or prompt.

Any one have any ideas?

Regards,
Spev

You can make DNS Host (A) record of File server in domain A on DNS server of forest B..
Also check if you are able to access file server with IP from domain B
You can telnet file server IP on TCP 445 from domain B computers \ servers and check if it works

Thanks

do you actually have a two way trust in place?? I would check the settings there first on both domains.

You can check one thing please..
if there is firewall exists between both domain file servers, just check that firewall can pass below netbios and SMB traffic
Netbios broadcasting
TCP 139  
UDP 137, 138

SMB
TCP 445

Thanks for the responses,

I manage to identify a CIFS transfer error on one of our Citrix Cloudbridge units. Once the traffic error was resolved the fault was resolved.
