Windows Credential issue

[Chintu1]

Hi All,

we are doing windows server discovery through out the enterprise network and it's working fine. But for one windows server we are getting credential Time out error, And we can able to login to the server using RDC. And we know there is no Firewall block and port 135 is also open for the server.

And when we run the simple WMI command from the MIDserver Host we are getting error like "No such Interface supported". So after reviewing the error from below KB article, it seems like Firewall issue, But the port is open.

So please me out to get this issue resolved.

Thanks in Advance.

Best regards

You might want to try running the same wmi query suggested in the above referenced KB article (gwmi win32_operatingsystem -computer 10.xx.xx.xx -credential 'Domain\User') against another system on the same subnet to verify the output. 

As all replies suggest, it is likely a firewall issue, be it host based, or network based. I would locate a resource that can watch the network traffic and tell you what's happening with the packets, and ports. In my experience that's been the fastest way to track these types of issues down.

Yes William agree with it. But it's taking longer time than usual for them to watch the traffic on this issue about the ports and packets drop in between MID and server..

Thanks,

Best regards
