Exchange System Attendant Startup Failure

Posted on 2003-11-28
Last Modified: 2007-12-19
Running Win2k SP4 SBS SP1. Each time I reboot the server I get the following error(s): The Microsoft Exchange MTA Stacks service depends on the Microsoft Exchange System Attendant service which failed to start because of the following error:
%%0. The remaining Exchange services also fail. Noticed from a previous post that the reply post requested info on the Netlogon service. This service does fail during startup as well with the following error: The Net Logon service terminated with service-specific error 2138. All of these services can start after the system is fully booted. Cannot find any answers regarding this particular problem. Any help would be greatly appreciated.

All the exchange services run using a domain account. If the netlogon service is not running they cannot be authenticated, and hence will not be able to start. When you reboot the server, does it stop pinging on the network, or does it maintain a steady ping and windows restarts. If this is the case the bindings on the LAN cards might have a few issues if they are not fully restarted. I have seen this style of issue on COMPAQ equipment. The 'quick' fix was to go a cold restart each time we rebooted the servers.

TO: (poi410) I tried the pinging of the server while it is rebooting and the network card does release not allowing my pings.
TO: (ikm7176) I did enble the Exchange logging to maximum, but could not find any other problems.
TO: (Vahik) This article did not pretain to my problem.

To ALL: I found that the NetLogon service is causing the Exchange System Attendant to start. The error shown for the NetLogon service not starting is that the Workstation service is not started. By the time I log into the system, the Workstation service is started. I set the recovery for the NetLogon service to continue to try restarting, but it still fails. This is causing the remainder of the Exchange services to fail. Any ideas?

After checking the security bulletin for MS03-049, I determined I was not infected with the listed vulnerability. I am running ISA Server 2000 with the vulnerable ports blocked. Also, I applied this patch a few weeks ago. I posted this problem on the Microsoft MCP Forums and did find the answer. The registry key for the NetLogon service dependant services was corrupted. After replacing the affected key, the server reboots normally. This was found in the Microsoft KB article:;en-us;269375&Product=sbs
Thank-you all for your help
