Proiblems accessing remote server - network path not found

 Hi all,

    We have a following strange problem - I have a set of SCCM servers (5 of them) and one distribution point in remote location (say distrPoinFQDN.sth.int). All of them are able to ping each other based on FQDN. Here is the situation:

1. We cannot reach \\distrPoinFQDN.sth.int from any of our SCCM servers (neither the root folder, nor any share on it)

2. We can reach any other distribution points and their shares from any of our 5 SCCM servers

3. We can reach \\distrPoinFQDN.sth.int from other servers in the remote location 

4. We do not see any drops on the firewall between the servers (only allows)

5. We see incoming packets from our SCCM servers on the windows firewall log of distrPoinFQDN.sth.int server

6. We can connect from distrPoinFQDN.sth.int server to the shares of our SCCM servers

    The error message we get is "Network path not found" So looks like I can connect to any server from SCCM servers, from any server to distrPoinFQDN.sth.int server, but only not from SCCM servers to distrPoinFQDN.sth.int. Any idea where to troubleshoot any further? Is it possible to somehow set permissions to root share \\distrPoinFQDN.sth.int\ which we didn't do? TIA for any suggestions
