As it is part of a domain, it is most likely done through stratégie de groupe, vous pouvez go vers le desktop as an administrator and open up the Group Policy Editor (Allez à Run and tapez MMC, ensuite allez à File > Add / Remove Snapin) and find Group Policy.
Take a look under Computer Configuration > Administrative Templates > Windows Components > Windows Update.
Si vous ne sont pas using stratégie de groupe, just take a look directly at le registre clé:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Vous devriez see the clés WUServer and WUStatusServer which should have the the locations du specific servers.
Il y a far too many clés and entries for me to write, but si vous are interested, Technet have an excellent article on all dum.
