    Code Block
    languagebash
    [base]
name=CentOS-$releasever - Base 
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra 
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ 
gpgcheck=1 
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 
enabled=0 

#released updates 
[updates] 
name=CentOS-$releasever - Updates 
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra 
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ 
gpgcheck=1 
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 
enabled=0 

#additional packages that may be useful

#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/

  2. Flush repo metadata.

    Code Block
    yum clean all
yum repolist

  3. Install an NTP Server. Do not use Active Directory as an NTP Server Source.
    “The W32Time service is not a full-featured NTP solution that meets time-sensitive application needs.”​

    “The W32Time service cannot reliably maintain sync time to the range of 1 to 2 seconds. Such tolerances are outside the design specification of the W32Time service.”​

    From Microsoft KB 939322

    Code Block
    yum -y install chrony

  4. Configure sync with local NTP Server.
