All Exchange server 2013 services not able to start

Description:

The Exchange services not able to restart and have the following event logs

Event ID: 10006
Source:  MSExchange Mid-Tier Storage
Description: Active Manager Client experienced an AD timeout trying to lookup object '' in 00:01:00.

Event ID: 2142
Source: MSExchangeADTopology 
Description: Process Microsoft.Exchange.Directory.TopologyService.exe (PID=) Forest Domain.com. Topology discovery failed, error details. No Minimal Required Number of Suitable Directory Servers Found in Forest Domain.com Site RNS and connected Sites..

Cause:
 Misconfiguration of the Active Directory Global Catalog as we have two options in order to make the Active directory work properly with Exchange which is at the same AD site:
Option 1: Have one Global Catalog server for Each site
Option 2: Have all Active Directory servers a Global Catalog

So incase we have four AD in the same site we cannot have only three of them Global Catalog servers.

Resolution:
Make sure you have correct number of the Global Catalog servers at this site
