Troubleshoot Active Directory Logon issue – By Anang Kumar

  • Note the error message (Sometime the error message is very specific )
  • Login to the machine using local admin account
  • Check the system Date and time / Time zone – Make sure they are similar to authenticating DC
  • Check DNS – Make Sure they are pointing to Right DNS (DNS which is alive and doing the name resolution)
  • Check DNS records with the help of NSLOOKUP
  • Ping the DC – IP, Netbios Name and FQDn
  • Ping the DC to DC with 1500 MTU
  • Run Netdiag and check DNS and Trust and Kerberos test
  • Make sure NIC card is enabled of “register me in DNS”
  • Check event viewer for any know errors like Userenv, Kerberos, netlogon
  • Enable netlogon log and do the further troubleshooting  

Don't forget to post your comments :)

Thanks,

Both the Certificate Authority Server Enrollment Agent (Computer) certificate needs to be added. They are added one-by-one. The Personal –> Certificate store sh...

A comparative analysis of application delivery methods - XenApp vs. ThinApp vs. App-V

What is application virtualization? I am attempting to answer this oft-asked question here. Besides application virtualization, let us look at various other methods of delivery too. The minor differences between vendors and their capabilities often confuse our decision-making. Let us see how my blog helps in addressing these questions and more. Let us first understand what the different types of Application Models are. Traditional Application Deployment Session Hosted Applications (SHA) Application Virtualization (AV ) The application is installed locally on to individual desktops and laptops, either using manual or ESD methods The application is installed on the server and only the screen pixels, keyboard and mouse clicks are sent back and forth between the server and the client The application is separated from the OS, aka profiling, and installed in a virtual container. The entire package is stored at a fileserver from where it is streamed to the client or the serv...
