GetPrivateQueuesByMachine - Get A List Of Queues From A Remote Machine
Dec 4, 2009
I'm using the 2.0 framework to get a list of queues from a remote machine. Sometimes the machine has a firewall and then the user has to wait 80 seconds or so before an exception is thrown stating that the machine is unavailable. Questions: Is there any way that I can set/change the timeout for GetPrivateQueues ByMachine? Is there any other method I can call before running GetPrivateQueuesByMachine to see whether the machine is responding? One that has configurable timeout, Any other solution?

I am having trouble reading the event log on another machine. From what I can gather the .geteventlogs("server01") method should return the logs from the computer named "server01" but it doesn't work for me. It returns the results from the local machine instead.

We're trying to write code to obtained all the logged on users to a remote machine.
We have the following, which only seems to identify users if they are logged in locally. However, if they're logged in through some other means (such as remote desktop), it doesn't seem to pick those users up.
How can we obtain all the users logged into a machine while excluding those users who only have a process running but aren't logged in (eg, a service is installed by them and might be currently running under their name)?
Dim WMIObject As String = "winmgmts://" & strComputerName.Text & "/root/cimv2"
Dim oComputerQuery As Object
'Contains a sorted list of every user logged into the system

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.

The conditions are I don't have administrator privilege I want to see the status of a service in remote machine (server)I use the following code (vb.net with framework 2.0) to see the status
Dim sqlSvc As ServiceController
Svc = New ServiceController(My.Settings.serviceName, My.Settings.machineName)
If sqlSvc.Status.ToString.Equals("Running") Then
displayStatus("success", sqlSvc.Status.ToString)
Else
displayStatus("error", sqlSvc.Status.ToString)
End If
When running the code, InvalidOperationException is raised and found out that I need admin right in the server.Can I lookup the status of the service without having admin right in remote machine ?

Dont know how easy this would be, but basically I'm just wondering if there is any way in VB.net you can close open files on a remote PC.In my scenario the vb.net app would be running with domain admin permissions in most cases so would have access to things like the remote Computer Management console, which of course has the Open Files section in it which lets you close any open files on the remote machine its connected to.So I fugured there must be some way to do it in vb.net... I just dont know if its going to be more hassle than its worth and I dont really know where to start looking (ive used googled but not had much joy).

I'm trying to execute a program on a remote machine using this code
Dim objProcess As New System.Diagnostics.Process
objProcess.StartInfo.FileName = "cmd.exe"
objProcess.StartInfo.Arguments = " /c PSExec /accepteula \NTAPPMTMIGL01 -u $AdminUsrLocal -p tjdsi44 c:winntMicrosoft.NETFrameworkv2.0.50727gacutil.exe"
[code]....
If I use it, it works since I'm an admin but if someone else use it, I got "The system cannot find the file specified."Is there any other program I can use that can impersonate, I've already tried xcmd.exe but it doesm't work either.

I am developing an Application in VB.Net 2.0. I have a module which would copy files from the Local Machine to a shared folder on remote machine. This shared folder on the remote machine is an authenticated folder. So, after searching on the Internet I found the following piece of code.[code]Another point to note is that when I connect to the File Share using Windows Explorer and then try to execute the application, it works properly.I am not sure why I am getting the error when I do not connect to the Shared Folder using Windows Explorer.Do I have to set some property so that the Credentials passed in the authentication are used.I also checked some posts that suggested setting up Mapped Drive to the Shared Folder on the Local machine and then to copy the file using IO.File.Copy function. However, I cannot use this as this Remote Folder should be only accessed through the application and not in any other case by the User. The users will not even have the credentials to this remote Server as it will be configured by the admin.So, Is there any way in which I can set this up and transfer the files from local machine to a remote shared folder?

I'm trying to replicate a design pattern used in a graphical programming language called LabVIEW. One thread produces commands, and another thread, or series of threads, consumes the commands.This is very similar to using Queues in VB...but there doesn't seem to be an easy way to start the consumer thread when new items are added to the queue.
Here is what I would like to accomplish, please let me know if there is a straightforward way to accomplish this with out of box .Net functionality.1) Start the Consumer Thread...it sits idle, waiting for some new commands to appear in its Queue.2) Producer places a few commands into the Queue. Example: "Home X Axis", "Home Y Axis", "Initialize Pump", "Display Ready Message"3) Consumer thread 'wakes up' at seeing the new commands, then performs the 4 tasks specified in 2.4) Consumer thread goes 'idle' again, and simply waits for new commands to appear in the Queue.
Process can continue on and on forever. The main problem I see with Queues is that there is no 'Wait for Something to Appear in Queue then Retrieve it" functionality. I don't want to use a perpetual loop to keep checking ever n milliseconds.

I am trying to use MessageQueues to notify users of an application of data changes using the Multicast feature, but can't get it to work : the workstation that sends the message does receive it, but none of the other running workstations seem to catch the sent message.Sending messages is done as follows :
Dim sendQueue As New Messaging.MessageQueue("FormatName:MULTICAST=234.1.1.1:8001")
Dim message As New Messaging.Message("message body...")
sendQueue.Send(message)
And receiving them :
Dim receiveQueue As New Messaging.MessageQueue(".private$myQ")
receiveQueue.MulticastAddress = "234.1.1.1:8001"
receiveQueue.BeginReceive()
[code]....
So I'm obviously missing something, and I can't seem to find any good ressources on multicasting with MSMQ 3.0 in .NET.Also, what is not clear is wether I should use a local queue per workstation, or one single remote queue on a server to multicast messages ? And does using the receive method on multicast messages purge them from the queue ?On a side note, all workstations are on the same subnet, and all have MSMQ 3.0 installed.
Despite what the Queue properties dialog says, permissions are NOT totally ignored on unauthenticated queues, at least when using multicasting. If you want your queue to receive multicast messages, it must give to 'ANONYMOUS_LOGON' the right to 'Send messages'. Otherwise, multicast messages are just discarded without any notice in event logs or whatsoever (unless I missed something).
On Win7 stations (XP stations seem to do fine, which is what pointed me to the actual problem), queues created through code do not have such permissions, and hence must be manually set after creating the queue :
Dim msgQ = Messaging.MessageQueue.Create(queueName)
msgQ.SetPermissions("ANONYMOUS LOGON",
Messaging.MessageQueueAccessRights.WriteMessage)
It would seem that internally, MSMQ uses that account to write multicast messages to unauthenticated queues.

IIS7 running on Windows Server 2008 R2. Development environment is VWDE 2010.
I'm setting up a simple "machine status" page to monitor a server. I want to display the Drives on the machine, including mapped network drives and show their free space, etc.
I'm using System.IO.DriveInfo.GetDrives() to return a collection of DriveInfo objects. I then itterate that collection to display the relevant information.
The issue I'm having is that only local drives appear. (A:, C: and D:) No mapped drives "Network Locations" appear in the collection.
I'm thinking it has to do with the user account that's executing the code (if that makes any sense). So if the code is executing under the user "ASPNET" (or whatever it is) the drives would have to be mapped under that user. As it happens, I have the server set up like a workstation and it logs in automatically under the user with the mapped drives.
What I've done:
- I have set the Web Site's Anonymous Authentication user to that same user
- I have set the Identity of the Application Pool to which my web site is assigned to be that same user.
