如何從一個域獲得其他域

我可以連接到一個特定的域，並得到其DirectoryEntry的是這樣的：

DirectoryContext dc = 
    new DirectoryContext(DirectoryContextType.DirectoryServer, "xx.x.xxx.40", "w28\\administrator", "pwd"); 

Domain domain = Domain.GetDomain(dc); 
DirectoryEntry entry = domain.GetDirectoryEntry(); 
foreach (DirectoryEntry child in entry.Children) 
{ 
    Console.WriteLine(" - " + child.Name); 
}

然而，當我嘗試通過森林properity拿到其他領域。

Forest forest = domain.Forest; 
Console.WriteLine("Count: " + forest.Domains.Count); //It crashes here 
DomainCollection domains = forest.Domains;

我的應用崩潰並且在下面示出的異常消息： System.DirectoryServices.ActiveDirectory.ActiveDirectoryServerDownException：指定的域不存在或無法聯繫。

在 System.DirectoryServices.ActiveDirectory.Locator.GetDomainControllerInfo（字符串 COMPUTERNAME，字符串域名，字符串SITENAME，Int64的標誌）在 System.DirectoryServices.ActiveDirectory.DirectoryContext.isCurrentForest（）在的System.DirectoryServices .ActiveDirectory.DirectoryContext.GetServerName（）在 System.DirectoryServices.ActiveDirectory.DirectoryEntryManager.GetNewDirectoryEntry（字符串 DN）在 System.DirectoryServices.ActiveDirectory.DirectoryEntryManager.GetCachedDirectoryEntry（字符串 DIST inguishedName）在 System.DirectoryServices.ActiveDirectory.DirectoryEntryManager.ExpandWellKnownDN（WellKnownDN DN）在 System.DirectoryServices.ActiveDirectory.DirectoryEntryManager.ExpandWellKnownDN（WellKnownDN DN）在System.DirectoryServices.ActiveDirectory.Forest.GetDomains（）在系統。 DirectoryServices.ActiveDirectory.Forest.get_Domains（）

請幫幫我。

在此先感謝。

我在我的森林中運行類似的代碼（通過GetCurrentDomain（）並查詢它的Forest），它們運行良好。我認爲問題就像異常和調用堆棧一樣 - 它試圖通過查詢作爲DC的森林根服務器來獲取有關您的森林的信息，並且無法聯繫它。我認爲你需要檢查你的拓撲結構，然後查看服務器的狀態。

我有這個相同的問題。我在域之外，而且我永遠都會因爲我們是網絡安全測試人員。

我發現這是一個很好的方法來解決
