Exchange server 2007 Hata

Aşağıdaki gibi çözdüm

Topology Discovery failed 0x80040a02

Debuging Exchange services can be hard. Even if Microsoft doesn't help with their Extensive and Easy to use knowledgebase.

Maybe I can help with this post.

Process WINMGMT.EXE (PID)=996. Topology Discovery failed, Process MAD.EXE Topology Discovery failed, error 0x80040a02. , Network Connections Service does not want to start, or everything that is weird after installing Exchange 2003 Server can be a security issue.

Thanks to wtb5 (even if I don't know who he is)

-At the domain controller open Active Director Users and computers.
- Right click on the domain container and click on properties.
-Click on the Group Policy tab, hi-light the default domain policy and click on the edit button.
-Expand the default domain policy tree: Computer configuration, windows settings, security settings, local policies, user rights assigned.
-In the right hand pane open the "Manage auditing and security log" policy.
-In my case I had to click on the Add button then the browse button, then find and select the ôExchange Enterprise Serversö user.
-Restart the Exchange server and things are working again!

... you don't even need to restart Windows! What a deal!
