with control keymgr.dll) or by search with a click on. If I try to start the Win10 Credential Manager (i.e. If(Test-Path "D:\Media\Sounds\Wav\Windows\TBONEWAH. Credential Manager - 0x800706BA - The RPC server is unavailable. Test-NetConnection -ComputerName $server -port 135įor older machines I have a function called tcping that works really well - haven't compared it to your Test-Port but it's probably similar. Test-NetConnection (PS 4.0 and above on Windows 8.1/Server 2012 R2) can do this natively. I have read about the try statement, but am a bit unsure on how it work or if it even if applicable to this situation. What I want to do is to first check if the RPC server is avaliable and then get the Wmi data. This means that then I run my script, select an OU and request a report, it will work fine until it comes to one of the machines that we can't access the RPC server on, then it will take a very long time for each of the Get-WmiObject lines (way longer then the ping test). The problem is that out network is set up in a way that we don't have RPC access to all computers (only a few are blocked) yet we can ping them. It then put's everything we need from the objects into a new object and dumps that in an array, which is then dumped into a CSV. It first gathers a list of all computers in the OU selected (I even wrote a GUI, fancy, I know), then pings a machine, if it gets a response it gets data with four Get-WmiObject lines (BIOS, ComputerSystem, OperatingSystem and PhysicalMemory. In the case of NetScreen (ScreenOS) there is a checkbox in the rule to allow NetBios.I am currently working on a simple inventory script, it generates a CSV file with all relevant data. In the case of WatchGuard you must specifically create a rule/policy to explicitly allow the RPC ports. Many firewalls (Watchguard) will block RPC and SMB/NetBios (NetScreen) even when you have ‘any-any’ rules in place. I can COMPMGMT.MSC to a remote PC and view Windows Logs, start/stop Services and use Performance Monitor but I cannot use WMI Control ('Failed to. Resolution: Work on your firewall policies to make sure RPC is not being blocked. Lansweeper and SpiceWorks running on the same server, virtualised Windows 2012, but this isn't really relevant as any two machines cannot RPC/WMI to each other. If telnet fails because the port is closed then it will simply time out as you can see in this example: If telnet is successful and the port is open then you will see a blank screen. You can also test specific ports, like 6007 using the telnet command. If RPC communications are working between the servers you will output similar to the following: If communications fail you will see output similar to the following: Get-WmiObject Win32_ComputerSystem –ComputerName OTHERSERVER Commonly 6007 is what is being blocked in this case.ĭiagnosis: You can test RPC connectivity from the server you are on to another computer/server using the following command: Background: RPC is categorized as the X11 protocol and is in the 6001 to 6032 port range.
