-Time/Time zone is correct.
-Removed WSUS.
-Configured IE correctly.
-Updates and regs already exist in my machine.
-"rootsupd.exe" is executed for several times already.
-"Restore_WU_XP_2003" has already installed in safe mode before.
-Using "config.ini" provided by you.
-Updated root certificates.
-Renamed "SoftwareDistribution" to "SoftwareDistribution.old". No security software exists in my computer.
-HTTP links is what I use to open MU.
-ProxHTTPSProxy is enabled.
But, when I have checked the all instructions...
...0x80072F78.
What should I do? Every time I went through a operation-needed step I went back to MU, only to be filled with 0x80072F78 without exception, even until now.
Any solutions?
