Windows Server 2008 build 4031 is a pre-reset build of Windows Server 2008. On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to the BetaArchive FTP, and was later released in the ninth set of his 33 Longhorn/Vista builds on 1 February 2020, alongside the main lab compile of 4085, the x86 version of 4083, the main lab compile of this build, its Lab06_n counterpart and build 5520. Unlike build 4028, this build uses the older i386 installation method.

Bugs[edit | edit source]

Installation[edit | edit source]

On some machines and virtualizers, you must format the drive outside of this build's setup, otherwise it will crash with an Unknown Hard Error bugcheck.
This build installs very slowly. To fix this, change the hard drive to IDE and the CD/DVD drive to SCSI.
This build cannot be upgraded to by normal means.

Upgrade[edit | edit source]

In order to upgrade to this build from build 4028, you must edit dosnet.inf in the i386 folder to ProductType = 2. Then you must replace the following files and directories from Windows Server 2003 build 3790 and start WINNT32.exe with the switch/NotUsingIBS.

\I386\WINNTUPG
\I386\WINNT32.EXE
\I386\WINNT32.MSI

General[edit | edit source]

When attempting to launch certain programs, CPU usage will jump to 100% for a few minutes before crashing the program.
When a program crashes, you will not get the crash report until the next login.

Autorun[edit | edit source]

Under some circumstances, the autorun program may display incorrect text (possibly the text used for dialogs on the OOBE).
