The attached VBScript allows you to set an Out-of-Office reply for another user on an Exchange 2003. You'll need the required permissions on the Exchange server to set a user's out-of-office (either Mail Recipients or User Options Management roles).
I found the script in the comments section of this Technet blog article. Special thanks go to the author (Bill Prentice) for sharing.
This script is only for Exchange 2003. Starting from 2007, the Powershell cmdlet Set-MailboxAutoReplyConfiguration is available.
You can easily convert an Exchange mailbox from one type to another through the Exchange Management Shell.
Set-Mailbox -Identity user.name -Type Regular
There are four types you can use to convert to:
The Equipment and Room types are used for reservations of meeting rooms and equipment (DLP).
When demoting a 2003 domain controller using dcpromo, you may run into the following error:
The error message is quite misleading as the real cause has got nothing to do with NETLOGON, but is in fact a DNS issue. You will most likely have the server's primary DNS pointing to itself using loopback address (127.0.0.1) or its own IP address.
You can correct the issue by having the DNS point to remaining domain controllers, and remove any DNS pointing to itself (i.e. loopback address or any other IP owned by the server being demoted).
There are two ways to see which Certificate Authority servers exist in your AD domain.
The AD group Cert Publishers contain the servers that are permitted to publish certificates to AD. As a consequence, this gruop will contain all servers that are CAs.
You can use the certutil command to view (and select from) a list of CAs in the current AD domain:
certutil -config - -ping
Note: type the command as-is, including all spaces and hyphens.
A window will appear, listing the CA name and the server it runs on.
It has always been a bit tedious to manage and customize Internet Explorer through group policies, especially when your network has different versions of Windows and/or different versions of Internet Explorer.
To reduce complexity of maintaining Internet Explorer in a network, since long, Microsoft has made available the Internet Explorer Administration Kit. This tool allows you to exert more control over Internet Explorer, its settings and its behaviour.

A bit of a hidden feature in Windows 8: you can actually "quit" Windows Explorer.
Right-click the (empty) taskbar while holding down Ctrl+Shift to reveal Exit Explorer as an additional menu item. Clicking it will then end Windows Explorer, leaving you with a blank screen, same as ending explorer.exe from the task manager.
You can then call up task manager (Ctrl+Shift+Esc), and start Windows Explorer again (File > Run > explorer.exe).
When attempting to log on with a domain account on a computer joined to a domain that has both 2012R2 and 2003 domain controllers, you may encounter the following error:
Additionally, an Event ID 4 on Source: Kerberos is logged. You can only log on using local accounts.
Mixed 2012R2 and 2003 AD environments require hotfix 2989971 to be installed on every 2012R2 DC. See the KB for a full explanation.
The hotfix requires Update 1 (2919355) to be installed first. The hotfix is also included in update rollup 2984006.
