COMException未知错误(0x80005000) - DirectoryServices

Question

我在我的一个应用程序上遇到错误,每个月发生几次,但本周发生了两次.当这种情况发生时,第一个用户加载应用程序并开始工作时,它总是第一件事(Web应用程序,3-4个内部用户)错误源于这个非常简单的方法,一旦失败,它将无法工作,直到我重启应用程序池.现在,我也以其他方式查询AD,但这是用户在早上开始工作时调用的第一个AD相关方法.

public DomainUser GetDomainUser(string userLoginName)
    {
        using (PrincipalContext context = new PrincipalContext(ContextType.Domain, this.DomainName))
        {
            using (UserPrincipal user = UserPrincipal.FindByIdentity(context, userLoginName))
            {
                // If user is null, the result is not a UserPrinciple
                if (user != null)
                {
                    string firstName = user.GivenName;
                    string middleName = user.MiddleName;
                    string lastName = user.Surname;
                    int empId = Convert.ToInt32(user.EmployeeId);
                    string emailAddr = user.EmailAddress;
                    string userName = user.SamAccountName;
                    DateTime? accountExp = user.AccountExpirationDate;

                    return new DomainUser
                    {
                        FirstName = firstName,
                        MiddleName = middleName,
                        LastName = lastName,
                        EmployeeId = empId,
                        Email = emailAddr,
                        UserName = userName,
                        AccountExpiration = accountExp
                    };
                }

                return null;
            }
        }
    }

所以这个问题是密切相关的,但我的权限设置正确,代码在99%的时间内工作,并将在应用程序池重新启动后继续运行.

堆栈跟踪看起来像这样:

System.Runtime.InteropServices.COMException (0x80005000): Unknown error (0x80005000)

   at System.DirectoryServices.AccountManagement.UserPrincipal.FindByIdentity(PrincipalContext context, String identityValue)
   at ADWrapper.AdSearch.GetDomainUser(String userLoginName)

问题是什么？内存泄漏？常见的模式是,当第一个用户开始使用应用程序时,这首先发生在早上.

我很长一段时间都在同一个问题上苦苦挣扎。我的解决方案实际上是安装功能IIS 6 Metabase Compatibility。之后就没有问题了。下面是一些对我有帮助的文章
