Server 2012 Foundation / HOSTS File

hi everybody,

i've got bit of situation 1 of customers.

this situation,

i've got server running 2012 foundation following roles:

domain controller (ad), dhcp, dns etc.

hostname: server
ip: 192.168.4.10
sn: 255.255.255.0
gw: 192.168.4.254
dns: 127.0.0.1

somebody(another company) added entry local hosts file on server.

192.168.4.10 -> portal.mycompany.nl

so because of entry overruled server it's name.

after entry server roles came tumbling down.

the dhcp servername changed portal.mycompany.nl , unable change dhcp settings , unable view authorized server.

also dns came halt, services kept on running not able resolve names.

the server showed events 404, 407, 408, dns related.

i deleted hosts entry , got dhcp , other roles back.

dns still broken , needed re-add server address forward lookup zones because local server address "unknown.

i had day of work running, company made hosts entry claims it's not possible source of problems.

they claim these settings on customers servers.

i can figure when add entry overrules servername stops working..

what's vision on if may ask?

with kind regards,

tim

hi,

>i resolved issues, need sure these issues due hosts entry, , if it's not allowed create such entry in hostst file.

according description,i think case.

you add such record in hostsfile,and mentioned,other company does it same , no error.the point iis service on dc.after add record in hosts file,it creates name resolving conflict,clients can't find dc.
