DNS settings and connectivity between 2 sites

[password1234]

Hi!

 

Question, maybe something easy or straight forward just been banging my head about this

 

2 Schools we have

 

School A based in City 1

IP Range:

[TABLE=width: 191]

[TR]

[TD=width: 191]10.52.26.0/23[/TD]

[/TR]

[/TABLE]

 

 

School B based 20miles away in another City

IP Range:

[TABLE=width: 191]

[TR]

[TD=width: 191]10.2.54.0/23[/TD]

[/TR]

[/TABLE]

 

 

Both Schools are connected via VPN we are using RM Broadband and connectivity between both sites work, School A has the main server which has a DC/File Server and everything else

School B currently we have got rid of the server for now and everything is running from School A, the school is running a single network

 

I logged in to School B Server today and able to ping the DC/host and everything correctly which sits on

[TABLE=width: 191]

[TR]

[TD=width: 191]10.52.26.240

 

However when i try to browse from School B via Server name i.e. \\school-dc01\ I am unable to reach it! i can perfectly browse through IP address but not host name

 

Anything i need doing? I am sure i have missed out something easy! Just cant for the life of me figure it out[/TD]

[/TR]

[/TABLE]

Are they on the same DNS domain. What happens if you ping the full server fully qualified domain name (fqdn) does it resolve to correct IP. Edited August 5, 2022 by Davit2005

Have you got DNS forwarders setup?

 

i.e. Does Domain 1 know that Domain 2 exists? And if so, which DNS server to contact to resolve addresses?

 

... and is there any AD trust in place? (assuming you might want that).

OMG! Yes you are right!!!! That worked, the old machine was still on the old domain not planning to move things over till next week!

 

rejoined one of the old machines to the new domain and worked !

 

Doh! Thanks both

Gosh something so simply overlooked!

What do you have for redundancy. RODC at the other site? if your site loses WAN connectivity how will users login.

 

Don't create a SPOF.

Yup thats the plan to build an RODC at the second site

 

Site one we using hybrid setup which has the azure ad connect client that syncs the AD users to 365

 

Plan is to have RODC at site 2
