Hello. I hope someone can help with the issues I have.
Im having problems with machines taking up to 20 minutes to logon to the
network, this does not affect all machines just random ones.(most
machines)
We have used a network sniffer to look at the traffic from the client
machines and for some reason the client authenticates fine with the local
domain controller, and know which site it is in, but then goes off talking
to
other domain controllers around the world in other sites. Im not sure if
this
is when it is trying to pull down the group policy, does anyone know why
this
would happen?
Also if I ping my domain name the reply changes every so often, and its
always from a DC in another country site, if we add a host entry for the
local DC to the domain name it fixes the issues on some machines.
Also on almost all machine I get the error in the event log “The
Security
System could not establish a secured connection with the server
DNS/blah.blah.blah.com. No authentication protocol was available.”
What does this mean?
I know that’s all a bit random so any help would be appreciated.
