I'm having trouble with an established production .NET2 service. The service collects process information and log files from various target computers. It runs at 80 sites without issue; mostly on Windows 2000, Windows XP, and Windows 2003.
Now, running against a Windows 7 target, an exception happens whenever the service attempts to read process information.
The code looks like:
Process[] procs = System.Diagnostics.Process.GetProcesses("10.11.12.13");
Info: The target computer responds to ping and the "adminUser" credentials exist on both the target computer and the service computer.
Exception information:
ex {"Couldn't connect to remote machine."} System.Exception {System.InvalidOperationException} [System.InvalidOperationException] {"Couldn't connect to remote machine."} System.InvalidOperationException
Data {System.Collections.ListDictionaryInternal} System.Collections.IDictionary {System.Collections.ListDictionaryInternal}
InnerException {"Couldn't get process information from performance counter."} System.Exception {System.InvalidOperationException} [System.InvalidOperationException] {"Couldn't get process information from performance counter."} System.InvalidOperationException
Data {System.Collections.ListDictionaryInternal} System.Collections.IDictionary {System.Collections.ListDictionaryInternal}
InnerException {"The network path was not found"} System.Exception {System.ComponentModel.Win32Exception}
Message "Couldn't get process information from performance counter." string
Source "System" string
StackTrace " at System.Diagnostics.NtProcessManager.GetProcessInfos(PerformanceCounterLiblibrary)\r\n at System.Diagnostics.NtProcessManager.GetProcessInfos(String machineName, Boolean isRemoteMachine)" string
TargetSite {System.Diagnostics.ProcessInfo[] GetProcessInfos(System.Diagnostics.PerformanceCounterLib)} System.Reflection.MethodBase {System.Reflection.RuntimeMethodInfo}
Message "Couldn't connect to remote machine." string
To troubleshoot this I disabled the Windows Firewall on the target computer, to no avail. Anyone have any ideas?
If anyone has any suggestions as to which steps and in what order I should be trying I am very appreciative for the assistance.
Update: I executed a "tasklist" command from the monitoring computer, passing the arguments to query the remote (target) computer and I was able to see the same type of process information that I am not able to get programmatically...
The command looked like:
tasklist /s 10.11.12.13
The returned information looked like:
...
notepad.exe 672 1 4,916 K
...
So, why can't .NET see the process information???
