#### DHCP Failover feature deployment
DHCP failover deployed on Windows 2016 server to ensure Disaster recovery
`Prior to enabling failover feature:`
DC1: 50% of the scope
DC2: 50% of the scope
In case of DC1 failure, only 50% of the scope at DC2 available for assigning IP address to Clients. Few clients did not get IP and have network access issues
`After enabling failover feature:`
Both DCs own 100% of the scope and were in sync about the address lease.


#### Logrotate issue
Application Issue faced and server was down and not reachable by SSH.
Server console was accessed through iLO to analyze the issue.
Found the disk was almost full.
On verification, it was found that log files were not rotated hence the disk size was fully utilized.
logrotate service was down. The configuration file found to have wrong configuration lines. The configuration was amended and old logs were manually purged to resolve the issue.



#### Application issues due to NTP client not in sync
An application which authenticates clients based on certificates was down. Client authentication was failing and the clients were not able to update data to the server. 
On troubleshooting, it was found that the ntp client in the server was not synchronizing time from the NTP server. Firewall rules were mistakenly enabled on the outbound direction. Firewall rules were supposed to be enabled only on the inbound direction.
Firewall rules issue was corrected to resolve the issues.
