I have a setup a domain on our test bench to test some disaster recovery
scenarios. It has 2 windows 2003 Sp1 servers. One server is a domain
controller and the second server is an exchange server 2003. Everything
was working fine. I tested a disaster recover scenario where I trashed the
exchange server 2003 and then rebuilt it again to see if I could recover it.
I made backups of the system state and exchange server database.
I have put this exchange 2003 server back on the test domain again as part
of the recovery process.
The problem I have know is that I can ping the domain controller from the
exchange server but I cannot do vice versa, meaning I cannot ping the
exchange server from the domain controller. I have checked all the network
settings and they are all fine. But if i create an AD account I can use
that account to log into the exchange server, so the domain part is ok., but
I dont know why i cannot ping the exchange server from the domain
controller. This causes me issues as I cannot install some remote backup
agents from the domain controller to the exchange server which I need to a
restore.
I have checked the event logs of the domain controller server and since I
have started to get this issue I have started to get the following warnings
in the system log:
Event ID: 40960
Source: LSASRV
The Security settings detected an anuthentication erro for the server
LDAP\<Domain Controller Server Name>. The failure code from Authentication
protocol kerberos was 'There are currently no logon servers available to
service logon requests'
I also got some ipsec events saying that the ipsec driver is started in
bymass mode. I have no idea why the ipsec message is appearing but I
disabled the ipsec service, but still get that event logs.
I also got some NTPClient messages about the W32time.
But I am more concerned about the LSASRV error log.
From this can anyone advise why the the domain controller cannot ping the
exchange server.
