Unable to ping computers via DNS domain name

I have two desktop computers and recently set up a third computer, a Windows Server 2012 box, for which I installed DNS on it and set it up as a domain controller. I was able to successfully set up each computer to be part of the new domain. There is a router, which goes to the outside world.



Issue:
I cannot ping the other computer via a fully qualified DNS domain name. I also set up an A-record, which neither computer can ping.



Domain: myoffice.com
Computers: ComputerA, ComputerB
Fully Qualified Names: ComputerA.myoffice.com and ComputerB.myoffice.com



Each computer can ping itself using the computer name or its fully qualified name. The server, however can ping either computer.




Each computer has the Primary DNS Gateway set to the server's IP address and the Secondary Gateway set to the router's IP address. The router provides all DHCP addresses.



I created a new A record in the DNS Manager in [DNS | | Forward Lookup Zones | myoffice.com] setting mail.myoffice.com to the IP address of the server. Neither workstation can see the new A-record. I even did an "ipconfig /flushdns", not that that helped.



Obviously, I am not doing something that I should do. How do I troubleshoot the problem(s)?



Update:
Each client computer can ping the IP address of the domain control and by its computer name, just not the fully qualified domain name of the server.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits,

apache 2.2 - Server Potentially Compromised -- c99madshell

So, low and behold, a legacy site we've been hosting for a client had a version of FCKEditor that allowed someone to upload the dreaded c99madshell exploit onto our web host. I'm not a big security buff -- frankly I'm just a dev currently responsible for S/A duties due to a loss of personnel. Accordingly, I'd love any help you server-faulters could provide in assessing the damage from the exploit. To give you a bit of information: The file was uploaded into a directory within the webroot, "/_img/fck_uploads/File/". The Apache user and group are restricted such that they can't log in and don't have permissions outside of the directory from which we serve sites. All the files had 770 permissions (user rwx, group rwx, other none) -- something I wanted to fix but was told to hold off on as it wasn't "high priority" (hopefully this changes that). So it seems the hackers could've easily executed the script. Now I wasn't able
