Few weeks ago, I had to un-join and rejoin one of my VM to our domain. Unjoin from the domain, checked. Rejoin to the domain, failed?? I know some of you may feel like " heh? is it that hard? " So no, it is not hard at all, but this was my first time I got below error (no screenshot, I forgot to capture one!) Issues : ERROR : The domain controller does not meet the version requirement for this operation. But before the error prompted, I needed to key in my Domain Admin credential, which (1) I am pretty sure it was correct, and (2) it means my VM was connected to the network, and able to talk to Domain Controller. Troubleshooting :  I tried to join to domain using command line as below :

So yes... After 4 months without new contents, so I started with this. It looks easier to do (well, it is), but before you do that, you may want to read this  to understand the difference between hostname and netBIOS, then starts to explore on when to use them, their limitations etc etc. I won't discuss here (or maybe not today). So let's back to the topic.   Description : Changing NetBIOS Name of A Computer. ComputerName : NetBIOS : How To Do :  Go to Start > Run , and type REGEDIT  Browse to Computer > HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > ComputerName > ComputerName At the right side, double click at ComputerName string, and put correct Value data .

This post will show on how to disable local drive mapping via GPO for Windows Server 2003 environment. Considering GPO will take precedence over Citrix policy, this setting will work on both RDP and ICA sessions.

This issue occurred to me a few years back, when we started enrolling Windows Server 2008. When I tried to change my Citrix XenApp server to another farm, CHFARM.exe crashed and I could not do it. Because I was using GUi rather than command line during that time, so I could capture below detail. I did not have any issues in changing farm for XenApp in Server 2003, and my home lab (with Windows Server 2008) also gave a positive result. As I only can see this error on Server 2008 (security permission on my home lab was more relaxed - UAC disabled) and but not on Server 2003 (and my home lab), thus to me it was safe to narrow down the root cause to security permission on Server 2008 (to be exact : User Acess Control) that cause the problem. Issues : CHFARM crashed in the middle of changing Citrix XenApp farm (on Windows Server 2008). Troubleshooting   RDP to the server, launch RUN , type secpol.msc , and press OK . (First hint) At this window, click at I want t
