Windows Server 2016 shares are not accessible on domain

I have installed a DC server (Windows Server 2016) in parallel to SBS server, to replace SBS. But, somehow I couldn't connect with shares on new server from any domain computer. I can still ping the new DC but I can browser shares. Error: Network resource is unavailable.

I checked the firewall inbound rules, form SMB to TCP. Its blocked and I couldn;t find any way to turn it on. Its says its controlled by system administrator.

Any help will be much appriciated

Your machines are joined to the new domain controller domain?

New server domain joined to old domain and  has replicated the AD from old server. I'm not sure what you are asking.

I think you need to remove the SBS server. The last time I investigated, SBS and another DC could not co-exist on the same network. We always migrated what we needed, removed SBS and then set up the new DC.

That is why I asked the question....thinking...you must have setup a new DC and domain. SBS is a standalone domain system.  Domain trusts for replication of AD only...it doesn't coexist with other DC's.  You need to remove from the domain.

Thanks for the update. I inferred from your question that you might have them on the same network.

What numerical error do you get with:  NET USE T: \\server2016\foldername ?

What machines are trying to connect ?  Any with SMBv1 running?

You can't form a trust from an SBS domain?

You can have additional Domain controllers (in an SBS domain), in fact you can have up to 74 of them :) the FSMO roles need to remain on the SBS server until it is retired though!

Regards,

Pete

found this in firewall rules SMB over TCP is blocked and I couldn't override by GPO rules to open the port. I'm unable to disable it.
