You need to check the logs on your domain controllers as something is wrong
there. When you rebooted the box and started the services back up they would
issue another call to the domain controllers and what ever threads were
blocked at the time freed up allowing you back in again.

Hi All,
Any help on this is very much appreciated!!
Right, here goes! I have two exchange servers which are both running on
Win 2k3 SP1. Exchange is 2003 SP1. One of my exchange servers comes to
a halt and the only way to get it back up and running is by hard
resetting the server! When this has been rebooted the server works fine
and reports no errors in the logs after the reboot. However, I am
getting the following event logs showing errors prior to reboot:
Event Type: Error
Event Source: MSExchangeSA
Event Category: General
Event ID: 1031
Date: 16/10/2006
Time: 1:35:46 AM
User: N/A
Computer: Exchange
Description: One of the System Attendant's task is blocked.
Function: CMonitoringTask::Work
After this is logged I get the following event logs:
Event Type: Error
Event Source: MSExchangeDSAccess
Event Category: Topology
Event ID: 2102
Date: 16/10/2006
Time: 1:35:46 AM
User: N/A
Computer: Exchange
Description: Process MAD.EXE (PID=2344). All Domain Controller Servers
in use are not responding:
{Lists all my DCs}
Event Type: Error
Event Source: MSExchangeDSAccess
Event Category: Topology
Event ID: 2114
Date: 16/10/2006
Time: 1:35:46 AM
User: N/A
Computer: Exchange
Description: Process MAD.EXE (PID=2344). Topology Discovery failed,
error 0xffffffff.
Event Type: Error
Event Source: MSExchangeSA
Event Category: General
Event ID: 9154
Date: 16/10/2006
Time: 1:35:46 AM
User: N/A
Computer: Exchange
Description: DSACCESS returned an error '0x80004005' on DS
notification. Microsoft Exchange System Attendant will re-set DS
notification later.
These event logs are repeated until my exchange box was rebooted and
once it had been rebooted all works fine. Server has been up and
running and showing no errors since but this is very concerning and I
have checked all Microsoft KBs and google groups.
Have checked the DNS settings, made sure that the server can see all my
DCs. Have also checked all the security and permission settings which
have been posted on here.
My other exchange server works fine and has not rebooted any issues or
problems like this and both were set up at the same time. The only
difference is that the other exchange server is my external SMTP server
and this server points all external mail to it.
Any help on this is appreciated. I dont know why it is happening on one
server and not the other! If you need more info let me know.
Thanks in advance
Amit
