.Net - Open Remote Shared Folder With Credentials?
Sep 26, 2011
I need to open a folder on a remote server with different credentials in a window (explorer.exe).I managed to do it with no credentials (my credentials), but when I do it with another username and another password than mine, it opens a prompt to enter a username and a password, and it says "access denied".
In the access log on the remote desktop, it says that I tried to connect with my own username, and not the other username I entered. So, the process obviously did not work.
I have a treeview control which is being used to browse various folder on the users system drive. It can also be set up to connect network folders using UNC paths e.g "serverfiles". At the moment I'm getting a list of Directories by using My.Computer.FileSystem.GetDirectories however this obviously fails when the folder is password protected.
Is there a way that I can get Windows to open the credentials dialog as you would see in Windows Explorer and deal with the credentials side so then the user name & password is cached as well?
I am building archiving system, I store the files on shared folder on windows server 2003, the shared folder protected by one user name and password ,on LAN I need vb.net windows forms to open file inside shared folder, how I could open the shared folder and in same time providing windows server 2003 with user name and password for the shared folder
I have to admit that I was sceptical it would work... but below is the code. I had to make a minor change to the code you suggested. Whenever I tried IPC$ it would return a 53 result code, even though I'm sure the share exists. So at the suggestion of another website I removed the share and just the computer name and this worked.
I'm having an issue here with making a WMI connection to a remote machine using specified administrator credentials.I have the WMI code inside a function, I pass it the computer's name and it returns the WMI information that I am requesting as a string (or in this particular case, an integer) from the remote machine. I'm positive it works, and returns the information I need using specified admin username/password. NOW, the issue I am having is related to (it seems) calling this function from a backgroundworker. [code] "Value does not fall within the expected range." I literally have no clue why this would throw that exception, yet when I call this function from lets say just a random button on my form, it works beautifully. The key here is that I need my WMI requests/processing to run in the background.
if you could see everthing but the thing I'm having trouble with the Public Shared Function(folder in 'Dim folder As nvironment.SpecialFolder' is the problem)
Option Explicit On Option Strict On Imports System.IO
I have a program written in VB.net 2003 that are folks run under alternate credentials. Inside the app there is an option to open a UNC path to a network share. We were running Windows XP SP3 and IE6. The code is simple just a call to the explorer.exe with /root,\UNCPath. After installing IE 8 onto the machine this no longer works. Best I can tell the code is still working but now being executed in non interactive mode so nothing opens up. You can however see a new spawned explorer.exe running under the system account for each attempt at opening a UNC Path. Any ideas what IE8 could have done to cause this behavior?
Public Sub Share() Dim managementClass As New ManagementClass("Win32_Share") Dim inParams As ManagementBaseObject = managementClass.GetMethodParameters("Create")
creating ones own folder structure through tree view similar to the windows explorer for a windows application,will the application work on all the systems over the network?? will the files added to the folders (of the treeview in the application),visible to all.or would the exe be required to be put onto the shared folder of every system?? what will be the exact architechture???
I found how to create a share in C# using the ManagementClass to create an object to reference the Win32_Share class and the ManagementBaseObject class to access the members of the Win32_Share class.My problem is that I want the "Everyone" permissions to default to Read only.When I set the share via Windows Explorer it works fine but the code in my C# application is allowing Full Control and Change permissions along with Read permission.I tried using the DirectorySecurity class but that blows away the Security permissions (under the Security tab)without affecting any Share permissions of the Everyone group (under the Share tab).I don't want to change the Security permissions, I want to change only the Share permission (you know, the permissions that appear when you hit the Permissions button on the Share tab).
NetShareAdd API from a VB.NET application (.NET version 2.0) and although I can get the API to just create a basic shared folder I now want to create a shared folder and specify its Share permissions (not NTFS permissions) as well, which means I have to pass in a SHARE_INFO_502 structure rather than just a SHARE_INFO_2 like I was previously doing for creating a basic share. I have spent over 5 hours solid just trying to get this working and am getting to the point now where I really cant think of anything else to try.I've encountered several problems whilst trying to make this work but the one I am finally stuck on is this: When I call NetShareAdd it returns the error INVALID_PARAMETER and the parm_ err object (which is supposed to specify which member of the SHARE_INFO_502 structure caused the error) holds the value 501. I know it is something to do with the security descriptor because if I comment out the line where I set the SHARE_INFO_502 structure's shi502_ security_descriptor field then the code works without an error (just obviously does not set the share permissons I want).I think posting all of the code here might be a bad idea as its currently over 150 lines long (yes that is only code for getting this API working...) so I'll just post my definitions of the SECURITY_DESCRIPTOR structure and the code I am actually using to call the various APIs involved: [code] Each of those API calls prior to NetShareAdd returns a non-error value in the Debug.WriteLine that is done after each one, but there is obviously an issue somewhere with the security descriptor.
i am doing a vb.net windows application. in that i am creating one folder and making it shared and also assigning shared permission to SYSTEM. My code is as given below.
If I have a 'Shared' object defined in the App_Code folder; is that object shared amongst all users/visitors of my website? Or is it shared on a per-user basis?I don't know if that makes sense or not; but I've got a puzzle/solver I'd written earlier that I'm trying to incorporate into a simple ASP.Net site. It's probably poorly written, but I'd used a Shared boolean to determine if a solution had been found. The code works, now as an ASP.NET site, but if two visitors to my site were both validating their puzzle at the same time, would they both be accessing the same boolean?
give me a function or class which have properties ?For example:I shared a folder (C:shared)
Dim clsObj as new clsSharedMonitor("C:shared") 'so that I can get its properties like: clsObj.FullPath() 'Full Path of folder that client are accessing clsObj.ClientIP() 'IP of computer which access to server
I need to find a folder that is shared between all users of a PC, every body being able to read/write to that folder and below, without any errors. I think that the folder "C:Documents and SettingsAll UsersShared Folder" would do the trick. How do I find the path to that folder, regardless of the OS used (Xp / Vista / 7) and regardless of the Windows language (With a french Windows, this folder is called "C:Documents and SettingsAll UsersDocuments partag").
All i am trying to do is read and write files to a shared folder on a network in visual basic (VS 2010). I can go to the folder through windows without a problem and without being prompted for a password. However when i try to do it through visual basic, it cant find the directory. Here is my small snippet of code that i (hope) is telling me that the program cannot connect to the folder. [code] Are there any known issues with VS 2010 that may cause this? Maybe something else in my code that could have an effect? This is in my form_load event though, so it is literally one of the first things that runs.
I use the following code in order to check if certin user exists in the DACL:
Dim l_managemantObject As ManagementBaseObject() = CType(securityDescriptor.Properties("DACL").Value, ManagementBaseObject()) For Each mObject As ManagementBaseObject In l_managemantObject l_name = CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Name").Value.ToString If CType(mObject.GetPropertyValue("Trustee"), ManagementBaseObject).Properties("Domain").Value IsNot Nothing Then
I built an application that runs alright on Windows 7 and and XP but when I tried that on my home computer (Vista Home Premium),at very start, it says Can not open shared memory region and then it quits.
I need to create a folder on a remote machine (The machine name and UNC path are stored in an Access 2007 database. Once the folder is created, I need to share it out with Everyone:Full Control Permissions?
