In last weeks PCSTATS Newsletter (#223) there was some confusion about the formatting of a key set of commands. Below is the correct interpretation of the three command lines.
"If you're running Windows Server 2003 with SP1 on your authenticating domain
controller, you might run into the issue where WindowsXP machines have problems
connecting to the internet or log onto your domain. The problem is usually due
to a corrupt policy store which is most often caused by an interruption to disk
writing, luckily the fix is rather easy.
Start up a command prompt (Start -> Run then type cmd and press OK) and from there type out these three lines, press the "Enter" key after every line.
REG DELETE HKLM\SOFTWARE\Policies\Microsoft\Windows\IPSec\Policy\Local /F
REG ADD HKLM\System\CurrentControlSet\Services\IPSEC /V Start /T REG_DWORD /F /D 1
After that's done restart your server and you're set. No more WindowsXP connection problems with Windows Server 2003 SP1 authentication domain controllers."
