Hi Experts, we recently acquired another facility to support, just trying to do some fact checking before proceeding, first off, we do now have a vpn tunnel between sites, both forests are at a 2000 forest functional level, if I'm not mistaken, both will need to be raised to a 2003 forest level before proceeeding, is there any negative impacts to worry about with doing this, all dc's and servers in both domains are either 2003, or 2008.<br />
&nbsp; &nbsp; Second, all I should have to do once I raise the forest levels is create dns forward lookup zones for each domain, and create the trust, is this correct?<br />
&nbsp; Thanks in advance for any advice/help!

creating a cross forest trust

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.

Microsoft Legacy OS

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
