Reboot does not work after update

Hi guys,
thanks for your help. I recently did a yum update on my rhel6.4 server. After this update, user logins take for ever and the reboot command does not work. When I do a reboot, the server hangs. Nothing happens.

Any help with this will be appreciated.

Thank you

First we shall try to see what's going wrong, for this you just restart your server, in boot loader menu, press e for grub editing and then search and remove rhgb quiet, press enter and boot your system using b, now you should be able to see system messages.

By removing rhgb quiet you will have better understanding of whats going before login prompt and machine will most likely tell you what is wrong if you are facing problems.

After detecting issue we shall see solution.

The two most common problems in this situation are:
1. Dependency on an unreachable network resource, ie, NFS, NIS, LDAP
2. Bad disk

Per the previous post, boot into "single user mode". This usually is done by adding 'single' to the boot command-line. (step by step instructions with screencaptures at the link.)
