1. Open Active Directory Sites and Services: On the Start menu, point to Administrative Tools, and then click Active Directory Sites and Services.
2. In the console tree, expand Sites, and then expand the site to which you want to force replication from the updated server.
3. Expand the Servers container to display the list of servers that are currently configured for that site.
4. Expand the server objects and click their NTDS Settings objects to display their connection objects in the details pane. Find a server that has a connection object from the server on which you made the updates.
5. Click NTDS Settings below the server object. In the details pane, right-click the connection object whose From Server is the domain controller that has the updates that you want to replicate, and then click Replicate Now.
6. When the Replicate Now message box appears, review the information, and then click OK.

Our database has more then 42 millions records. We need to create reports for different roles.
I prefer opensource BI since we can build the website on our own server and access data directly.

1. Upgrade packages to the latest version

   sudo apt-get update && sudo apt-get -y upgrade
   

2. Install python-pip

Symptom

Add a network share folder in /etc/fstab

//windows-server/shared /mnt/shared cifs  iocharset=utf8,credentials=/root/.naspasswd,dir_mode=0750,file_mode=0750  0 0

Most time it works well. But every few days or weeks, the connection or the mount point seems to go dead or hang, such that any process that tries to access the mount point gets stuck in D state (disk, or I/O wait). those processed become impervious to TERM and KILL signals. The frozen state lasts for 5+ minutes.

Brew Install

  brew install ansible
  

When I installed McAfee Antivirus Enterprise v8.8 on a Windows 8.1, it was hung. Checked the log @ c:\users$user\AppData\Local\Temp\McAfeeLogs and found a messge “Waiting on McShield to report RUNNING or STOPPED (current state 2)” in installation log.

Two commands can be used

• tasklist – check process name and id
• taskkill – kill process

Some services are denied administrator to access on Windows such as McAfee services. I don’t know why administrator cannot manage every thing on Windows system. I think vrius maker and hacker already know this technology. How does administrator fight with them?
