Problem with Exchange server

have you looked at the exchange queue (toolbox in the exchange management console) to see what is happening?

Thanks.
Yes, I can see the mail I tried to send yesterday, within "Sent Item" folder.
Where is the log file to check any errors of the Exchange server?

Where is the log file to check any errors of the Exchange server?

Any help?

have you looked at the application log for any exchange warnings or errors?
are you receiving any mail at all to your server?

How to locate any errors in the log within Exchange server?

control panel -> administrative tools -> event viewer
look at the application log for any exchange-related warnings and errors

Sorry, where to find out more details for the error highlighted in Fig 2?

that's a problem...is that domain controller functioning properly?  are any domain controllers available?

What to check concerning domain controller?

is it working? are there any errors in the event logs? can the exchange server ping and do dns queries to the domain controller?  there is a communication problem between the exchange server and domain controller

What commands to check for these? thanks

look in the event viewer the same way you did on the other server
specifically the directory services log
how many domain controllers are there?

Where is directory services log located at? thanks

in event viewer, expand custom views, server roles then active directory domain services

Sorry, I do not see any error in that (in Fig 3)

can you ping the domain controller from the exchange server?
does anything resolve with nslookup?

Yes, I am able to ping that like

C:\Users\Administrator>ping WIN-BVDIC8GIAHI.win08.huamin.com

i'm concerned with the name resolution here
do you have a private ip address space?
i would expect the exchange server to resolve with private address, not the public internet address which could be the reason why exchange can't talk to the domain controller because it's resolving the wrong ip address

The server is now having 2 IPs. One is private like
192.168...

the other is pingable like
?.?.248.250

do you think I can disable the 2nd connection to see if it is fine?

Thanks. the server is being runnning as a VM, with Adapter 1 having "Internal network" and having IP like "192.168...", while adapter 2 is a Bridged adapter that is having the IP allocated by the ISP. hOW to detect/avoid any traffic issue concerning the firewall in this?

Hi,
Here is what I get now

C:\Users\Administrator>nslookup
Default Server:  localhost
Address:  ::1

>

what to adjust?
