I was doing analysis on my exchange relay server where Sometimes ldap query takes too long .
I ran process explorer and saw following:
I see high count on following.
1) Edgetransport.exe
2) MS Exchange transportlogsearch.exe
3) Microsoft.exchnage.monitoring.exe
4) W3wp.exe-I have no idea why w3wp is running on relay server
Yes, Exchange heavily depended on AD. When designing Exchange environment, make sure you have sufficient Domain controllers, which can take Exchange server load. This is one piece 95% admin doesn't consider, when installing Exchange servers. Best to have Exchange on different AD sites, with its own dedicated DC's.
