site2site vpn and issues joining domain

[password1234]

Hi Guys

 

Staff are back in one of the primary schools we support something has changed over the holidays which meant there was issues logging on

 

So here is the setup

 

Junior

Infants

 

(both within 100 meters of each other)

 

At the moment there is a site 2 site VPN between both sites with each site has its own router supplied by RM and everything has been working perfectly fine over the past year or so!

 

Junior site:

HOST SERVER

DOMAIN CONTROLLER 10.3 range (DHCP/DNS/)

FILE SERVER

 

INFANTS SITE:

DHCP SERVER only on a 10.139 range with DHCP pointing to the DC on junior site

 

all boxes running 2019

 

So the problem is today we came in and all of a sudden drives were not mapping and we were not able to domain join any machines, internet works perfectly fine, we take the laptop to the junior site and try rejoinin the domain everything works fine no issues whatsoever!

 

 

From Infant Side i tried to ping the following (From the DHCP Server)

Host - Works!

DC - Works!

File Server - dont work

 

Then i logged on to one of the admin machines ran another ping and got the following

Host - Works!

DC - Works!

File Server - work

 

They are all on the same switch!

 

DNS/DHCP and everything is okay nothing has changed over the holidays or so

 

at a loss at what could be the issue here, i've asked RM to check the site to site vpn incase any changes has been made so waiting to hear back from them

 

really really weird

Did RM come back to you regarding the issue. Would be interested to know what the issue was

Yup they did! Over the summer they made some Config changes on the router and site to site vpn (without notifying us) which broke the VPN connection! so had to get them sorted in the end

 

frustrating as we were out onsite for 2 days solid trying to figure out if it was an internal issue and all along it was RM!
