I used WMIC and I got error: RPC server is unavailable - windows

I would like to use WMIC and get products information about all PCs.
So I tried:
wmic /node:"IPAddress" /user:"domain\administrator" /password "Password" /output:c:\test.txt product get name, vendor
It does not work with all PCs.
I got error: Description = RPC server is unavailable.
Is there any idea to solve this problem??
And the service is running (Remote Procedure Call)
Thank you for your help.

Probable reason:
Firewall configuration (RPC connections blockage)
You don't enough permission to run WMI queries.
Machine is not reachable. Try pinging the machine.
Second point is valid if you are trying to run queries on remote machines. You can use wbemtest to verify.
Windows+R (run command)
Type wbemtest
Once UI is opened, try to connect to the machine which is throwing exception.

How to restore access to a windows shared folder after host password change?

I have a shared folder on a windows 10 host machine. I could access it from a windows 10 client machine, where I had set "remember credentials" when first accessing the share. I changed the password on the host. Now the client cannot access the shared folder. That was expected. But I could not find a way on the client to allow the user to re-establish access to the shared folder.
I expected it would ask for credentials again. However I got a network error saying that windows cannot access the host machine.
Based on a number of entries on various forums, I tried a few things. The credentials manager on the client does not show the host. I stopped and restarted file and printer sharing on the client, without any change in the result. Network diagnosis and the windows troubleshooter gave no help.
The problem was due to some previous connections remaining in the network table, even though disconnected, as presented by the "net use" command from the command prompt.
>net use
Status Local Remote Network
--------------------------------------------------------------------------
Disconnected \\192.168.1.71\IPC$ Microsoft Windows Network
Disconnected \\HOST\IPC$ Microsoft Windows Network
After deleting them (via "net use /delete") the next attempt to access the host asked for credentials. Yay!
I began the path to the solution when I tried
net use z: \\host\shared /user:admin password
which gave system error 1219 stating multiple connections to a server are not allowed. Disconnect all previous connections and try again. Obviously, even though known to be disconnected, the entries prevented reconnection.

SQL Server 2016 linked Oracle Server - Suddenly stopped working

After rebooting my Windows Server 2016 Standard (SQL Server 2016) my SSIS process that runs this query:
select * from openquery(HRMPROD, 'SELECT QUERY HERE' )
started failing with this error:
I get the same error if I try to run the query in SSMS. I have the same linked server set up on my test instance and the query is successful when I run it there. I have compared the linked server create script on both instances and it is the same.
Any idea where I should look for what is causing the connection issue on the one server but not the other?
Thank you.
Saying the answer is on the Oracle side is just like pointing fingers across the way. Let's just fix the issue here.
There is a connection string that is used from SSIS, (which you also used in SSMS) The connection string contains three main components to connect and would result in the 12154 error if any of them were incorrect:
Host
Instance name (different than Instance on Sql Server, think database name)
port
The port most likely hasn't change, neither has the database name, but the host...No, hasn't changed, but the DNS server used to connect most likely has! I would ping the host and see what returns from the SSIS and your SSMS host that you're using. I would expect it to fail. Find out what IP address the host is using and ping that - see if it returns. I'm guessing that's the change that needs to be updated or your Network folks need to fix a DNS configuration/server issue.
Hope this helps!

Since you are getting a response from the TNS Listener, the problem lies on the Oracle side. See Architecture of Oracle Network Services for an overview of how the Oracle networking handles things. Keep in mind that based on the error message you've reached the TNS Listener, so you only need to check things between TNS and the Oracle database... In other words, your networking and SQL Server settings are fine or you wouldn't be able to get this error message.
I would agree with above that the issue might have to do with the network. I have come across that a few times, where we can set everything up, but a firewall is blocking communication between the two servers.
Open up powershell on the new server and run a tracert to the target to see the hops and identify if is connecting across the network.
If it is, then run a test-netconnect on the specific port, to see if the port is open from the firewalls.
Cheers!

Error while querying registry remotely

I am trying to understand the reason why I cannot query a registry remotely.
I started REMOTEREGISTRY service on both the machines but still I get an error saying The network path was not found.
Whereas I can get the result from the other machine.
EDIT: Moreover when I run a SC query for this machine, I get an error The RPC server is unavailable.

Check if a remote desktop connection is active in Windows 7

As part of a business solution we are offering several remote desktops to a user base. Currently the users must go system by system attempting to connect and find one that is not already being used. I'd like to see if there is a command that can be run to quickly query an IP and see if there is an active remote connection already.
I've run across a 'wmic' solution already, but this only seems to work if the person running the command has admin access on the destination machine. I don't need a username returned or any information other than if there is a currently in-use remote connection.
Any idea's?
Researched solutions that didn't pan out listed below:
wmic /node:IP ComputerSystem GET UserName ---Returns only if requestor is an admin
qwinsta /server:IP ---RPC is not enabled on all machienes
eventvwr IP ---Too technical and time consuming for end users
Thanks in advance
query session /SERVER:servername

windows service command RPC error (sc.exe or psservice)

I am getting the following error when i try to run the command from remote machine
C:\>sc \\machinename query
[SC] OpenSCManager FAILED 1722:
The RPC server is unavailable.
I have admin privileges to that machine.
Any solution let me know.
In my case I got this error because I was messed up the name of the server I was targeting. It will give you this error if you accidentally point it at nothing. In my case, the server name was a variable being defined from a text document so it took a while for me to realize.
Also noteworthy: There should actually be two slashes before the machine name (I'm sure it's just a typo, but just in case it could confuse anybody).
The error 1722 is : The RPC server is unavailable.
Verify if RPC service (Remote Procedure Call (RPC)) is running at remote machine with telnet, try at command line:
*>telnet your.server 135
If no errors occurs the RPC server is probably ok, than check system events for issues.
6 years later but anyaway.
Enable File and printer sharing on the remote computer and it will work.

I tested on my localmachine
I tested from another machine on the network
SC is nice..! :)
You need to make sure that the Client DNS service is not stopped. This fixes the problem.
