Restore Windows Update for Windows XP / Server 2003

The Microsoft Update Site does not work. The Windows Update Site does work. Please help. Not in Windows XP, Server 2003 and Windows 2000.

 

Use windows update legacy restored

 

Why? Microsoft Update does only not work. Windows Update works perfectly. I will try an another methode.

 

@plangg

Could you expand on that? Maybe some screenshots...
Did not fully understand, my bad.

@pm67310 did give you a valid option.

 

The new v6-legacy-muauth.cab is sha2 signed only (old was dual sha1/sha2 signed), probably NT 5.1 can't verify it
check WindowsUpdate.log

 

How can I add the SHA2 Certificate?

The WSUS for 2000 and XP works fine and I become Microsoft Updates too.

 

check WindowsUpdate.log to see if the error is related to digital signature verification

yes, WSUS (real or proxy) doesn't use or need muauth.cab

 

In the Zip File is my windowsupdate.log. Please help me analyze the file

 

Is this Windows 2000? i believe it does not support any SHA256
because it cannot verify the new muauth.cab, it uses the current old muauth.cab, which has expired registration for MU service
it will never work

Code:

Error: 0x8009200d when verifying trust for C:\WINNT\SoftwareDistribution\AuthCabs\authcab.cab
Digital Signatures on file C:\WINNT\SoftwareDistribution\AuthCabs\authcab.cab are not trusted: Error 0x8009200d
FATAL: Service 7971F918-A847-4430-9279-4A52D1EFE18D requested, but it is expired

 

A little Update: legacyupdate is showing Microsoft Updates too under Windows 2000. How does it work?

 

legacyupdate is WSUS Proxy behind the scenes

 

Which, unfortunately, does not have the updates for stuff like Office 2000. Ask me how I know.

 

Yeah, Office XP category is the first one in current WU
