Not a valid Win32 FileTime

[GoogleCodeExporter]

I'm getting this error when I try to enumerate sessions on 2003 server. 
The remote server is not under any heavy load.

Exception calling "GetSessions" with "0" argument(s): "Not a valid Win32 
FileTime. Parameter name: fileTime"

It happens many times and I need to close the connection and connect 
again, which doesn't always resolves the problem.

I have the exact same issue on a 2003 Terminal Server.  Currently I just keep 
retrying the connection until it works.  This server is normally under a small 
load 
with 5-15 connections on it most of the time.

Oops, I thought that this issue had been replied to -- sorry for the late 
response! 
This issue should be fixed for Server 2003 on trunk. The trunk is quite 
stable, so if you'd like, you can grab the latest build from the build server 
(http://teamcity.codebetter.com/project.html?projectId=project51 -- use the 
artifacts 
link) and give it a shot.

I was using the dll from your link and still had the error.  Am I using the 
code 
incorectly?  Below is the function I am using:

 Public Sub TSLogins()
        ListView1.Items.Clear()
        Dim strTSADMIN As ITerminalServicesManager = New TerminalServicesManager
        Dim strTSServer As ITerminalServer = strTSADMIN.GetRemoteServer("\\server03")
        Dim strTSSession As ITerminalServicesSession
        Dim strTSInfo As String = ""
        Dim strTSTotal As String = ""
        Dim strTSState As String = ""

        strTSServer.Open()

        Dim strCounter As Integer = 0

        Dim item1 As New ListViewItem
        Try
            For Each strTSSession In strTSServer.GetSessions '*****Here is where I 
get the error******************
                strTSState = ""

                If strTSSession.UserName.Trim.ToString <> "" Then
                    strCounter = strCounter + 1
                    item1 = New ListViewItem
                    item1.Text = GetUserInfo(strTSSession.UserName)
                    item1.SubItems.Add(strTSSession.UserName)
                    item1.SubItems.Add(strTSSession.LoginTime.ToString)
                    ListView1.Items.Add(item1)
                    strTSInfo = "User: " & strTSSession.UserName & "    Logon 
Time: " & strTSSession.LoginTime.ToString & "  State: " & 
strTSSession.ConnectionState & "    Session ID: " & strTSSession.SessionId

                    strTSTotal = strTSTotal & strTSInfo & vbCrLf
                End If

            Next
            strTSServer.Close()
            strTSServer.Dispose()
        Catch ex As Exception

            strTSServer.Close()
            strTSServer.Dispose()
            Application.DoEvents()
            'System.Threading.Thread.Sleep(100)
            TSLogins()

        End Try

        Label2.Text = strCounter

    End Sub

Is it the "Not a valid FileTime" exception you are getting, or a different one? 
You 
said server03 is running Windows Server 2003? What version of Windows is the 
computer 
executing the code running?

I tried to reproduce the error today, and of course I was not able to.  The 
error is 
totally random and I have not been able to find what's causing it.  The error I 
was 
getting is "Not a valid Win32 FileTime".  The application is normally run 
directly 
on the  a terminal server (2003).  That is also the same server that I am 
gathering 
information about with the dll.  I am developing the application on an XP SP3 
machine and have gotten this error with both machines.

Here is the stack trace if this helps.  I was just able to reproduce the error. 
 I 
did try a few other times this morning and could not reproduce it.

Thanks for looking into this. Based on that stack trace, it looks like you are 
running 
the 2.0 release (2.0.0.60). Could you check the exact version of the assembly 
you are 
using? The latest trunk build is 2.1.0.93, and it should not have this problem 
-- not 
with that stack trace, anyways.

Sheesh!  I thought I did that, but I did not see that it extrated the dll in 
/bin.  
Anyway you are correct and I was using the old ver.  I just startet to use the 
new 
version.  Thanks so much for the help.

No problem. I am going to close this issue unless scriptolog has anything to 
say about 
it.

I've downloaded the beta build and didn't encounter the error again, though I 
didn't
test it extensively. You can close the thread. Thanks!
