it needs an old version? i've tried it before. when was wsus last updated? i dont think it should differ if i just tried it for xp rtm and all other versions and it worked just fine for me.
wsus still works with the current version, idk what you are on about with older versions but wumt.exe looks kind of broken on windows 2000 but still functions.
hey, please re-enable firewall back, it was prob unnecessary and your wsus could've worked just fine with it because it already has itself added as an exclusion although i thought firewall was still blocking it because i didnt get ping requests at all. dont worry if you do a first scan, just make sure you get a response from the client to the other xp server running in php.exe, if you do then its working perfectly fine.
hey, make sure to run the root certificate update by alvaro just so you dont run into any other problems with certificates, it seems to be up to date to around 2017. the root certificate update i gave you is from 2007 and is pretty old but has the certificates required for windows update so thats why it worked.
@mirroreduser you didn't use any certificate updater? probably some update cause it to be installed automatically anyway, whatever work
Nevermind, the lastest version of WUMT isn't compatible with anything older than windows 10 i've found the other version, gonna link it soon
