I have already setup a domain which i now know is wrong. The local domain is vdasrv.volunteering-ni.org which is of course a sub domain. And one of my servers is vdasrv.vdasrv.volunteering-ni.org. My main problem with this is when one of the servers is down users cannot logon to the system.
What i am doing now is installing a new email server. I want to set it up in the volunteering-ni.org domain then the other servers up to the same level. Does anyone have any help regarding this.
