Hello to everyone,

Anyone knows why i cannot telnet to ports 3268 and 3269 on my dc's or gc's ???

Even if i try to telnet localhost i obtain a connection refused message.

Thanks in advance.

I would expect because a machine you think is a GC isn't a GC or it isn't
working properly or something is blocking the traffic.

Note that at best you will get a connection with telnet, you won't be able to
really do anything or see anything.

run LDP....connect....and see if the following is set:
isGlobalCatalogReady: TRUE --> DC = GC
isGlobalCatalogReady: FALSE --> DC =/= GC

if it is a GC... disconnect, connect but use port 3268

Thanks to both

more data:

In my hub site i have 5 DC's, only one answer to telnet, this one is a GC, i
have 2 more GC's (both of them doesnt answer), the other 2 servers (not gc's)
also have the "problem".

With LDP: funny thing because with all the 3 gc's i have:
isGlobalCatalogReady: TRUE --> DC = GC

The funny thing is that if in the Connection options I leave the server name
in blank and change the port to 3268 i can connect, but if in the server name
box i type the name of the server i have a Error <0x0> Fail to connect to
%servername%

I use telnet to make connectivity tests

Thanks again

The name of the server that you type in ldp and then cannot open
connection.....have you ran portqry ui on that and checked if 3268 is
listening or not. You may want to check if you are locally filtering out that
port or if any third party service is blocking it. Doing an ms-config and
stopping all third party service may help.

Get out a network sniffer and then try to connect to 3268 and look to see what
is returned.
