为什么不同主机上的 SPN 会导致服务器失去信任？我该如何解决？

Question

我有一个全新的服务器映像，一旦加入域，它就会失去信任。我怀疑这是因为我使用此 Powershell 脚本的 LDAP 版本发现了重复的 SPN

Powershell 脚本

#Set Search
cls
$search = New-Object DirectoryServices.DirectorySearcher([ADSI]“”)
$search.filter = “(servicePrincipalName=*)”
$results = $search.Findall()



#list results
foreach($result in $results)
{
       $userEntry = $result.GetDirectoryEntry()
       Write-host "Object Name = " $userEntry.name -backgroundcolor "yellow" -foregroundcolor "black"
       Write-host "DN      =      "  $userEntry.distinguishedName
       Write-host "Object Cat. = "  $userEntry.objectCategory
       Write-host "servicePrincipalNames"
       $i=1
       foreach($SPN in $userEntry.servicePrincipalName)
       {
           Write-host "SPN(" $i ")   =      " $SPN       $i+=1
       }
       Write-host ""

} 

具有重复 SPN 的主机

我刚刚创建的主机

dn: CN=nyc01excas04,CN=Computers,DC=hp,DC=com
changetype: add
servicePrincipalName: WSMAN/NYC01EXCAS04
servicePrincipalName: WSMAN/NYC01EXCAS04.hp.com

servicePrincipalName: HOST/NYC01EXCAS04
servicePrincipalName: RestrictedKrbHost/NYC01EXCAS04.hp.com
servicePrincipalName: HOST/NYC01EXCAS04.hp.com

题

1. 什么会导致这些条目位于错误的主机上？

.

servicePrincipalName: TERMSRV/NYC01EXCAS04
servicePrincipalName: TERMSRV/NYC01EXCAS04.hp.com
servicePrincipalName: RestrictedKrbHost/NYC01EXCAS04.hp.com
servicePrincipalName: HOST/NYC01EXCAS04.hp.com
servicePrincipalName: RestrictedKrbHost/NYC01EXCAS04
servicePrincipalName: HOST/NYC01EXCAS04

2. 这些条目的含义是什么？它们是做什么用的

3. 他们会不会在新机器中造成信任失败？为什么只有一台机器有问题，而另一台机器没有问题

4. 如何更正问题？

Answer 1

基本上，setspn在正常运行的 AD 中不会显示重复项。我认为至少对于有问题的机器你应该删除它们。从有问题的机器 SPN 开始，它错过了领域部分。
