Question

当调用CreateFile（）函数时，它返回错误代码0x5，这意味着访问被拒绝。任何人都可以帮忙解决这个问题吗？

注意：CreateFile（）读取快照的路径，文件路径是\？\ globalroot \ device \ harddiskvolumeshadowcopy35 \ program files \ common files \ microsoft shared \ web server extensions \ 12 \ admisapi。

非常感谢。

Answer 1

您可以手动创建该文件吗？这很可能是一个许可问题。

Answer 2

这意味着您没有足够的权限从此文件中读取。检查文件权限。

Answer 3

访问被拒绝，您的应用程序在哪里尝试创建文件？如果它在程序文件等中，可能是因为它的Windows 7和用户无法创建它而不首先提升权限。此外，请确保它在您认为的位置创建它。

ConnectionOptions connection = new ConnectionOptions();

//just username, without domain name, otherwise, a "RPC is Unavaliable." exception will be thrown.
connection.Username = "testUser";

connection.Password = "testPassword";

//Allow privilege
connection.EnablePrivileges = true;

connection.Impersonation = ImpersonationLevel.Delegate;

connection.Authentication = AuthenticationLevel.Call;

//Neither ntdlmdomain or kerberoes， otherwise, a "Invalid Parameter." exception will be thrown.
connection.Authority = "ntlmdomain:MYDOMAIN";

//IP Address or host full name.
ManagementScope scope = new ManagementScope("\\\\myIPAddress\\root\\CIMV2", connection);

scope.Connect();

ManagementClass classInstance = new ManagementClass(scope,new ManagementPath("Win32_Process"), null);

ManagementBaseObject inParams = classInstance.GetMethodParameters("Create");

//Change it to your own execute file path
inParams["CommandLine"] = "myExecuteFilePath";

ManagementBaseObject outParams = classInstance.InvokeMethod("Create", inParams, null);
