WMIC/WMI Datasource against Domain Controller

I have problems querying WMI against domain controller in multiple domains. My account used for queries is in the DomainAdmins group (wanted to eliminate all group issues). Windows firewall is not enabled. Network is wide open between Zenoss and the server. All of the member servers of the domain respond fine to wmic. User/Pass are correct (not an access denied)

 

It looks like it has something to do with not being able to open pipes on a domain controller:

 

 

[librpc/rpc/dcerpc_connect.c:790:dcerpc_pipe_connect_b_recv()] failed NT status (c00000b5) in dcerpc_pipe_connect_b_recv

[librpc/rpc/dcerpc_connect.c:329:dcerpc_pipe_connect_ncacn_ip_tcp_recv()] failed NT status (c00000b5) in dcerpc_pipe_connect_ncacn_ip_tcp_recv

[librpc/rpc/dcerpc_connect.c:790:dcerpc_pipe_connect_b_recv()] failed NT status (c00000b5) in dcerpc_pipe_connect_b_recv

[wmi/wmic.c:196:main()] ERROR: Login to remote object.

NTSTATUS: NT code 0xc002001b - NT code 0xc002001b

 

Again this is on more than one domain. Has anyone experienced this? Other posts have indicated firewall but that isn't the case here.

    Re: WMIC/WMI Datasource against Domain Controller

    Stevez, Are you able to use wbemtest either locally, or from another windows machine to invoke a WMI query? Something like 'SELECT LastBootUpTime FROM Win32_OperatingSystem' should be a sufficient test.

    Re: WMIC/WMI Datasource against Domain Controller

    Hi dpetzl,

     

    I went on the domain controller and ran wbemtest. It ran and I clicked connect. It connected without any credentials with a namespace of root\default. I then clicked the Query... button which gave me a dialog box for a WQL statement. I entered the one you suggested and got Invalid class. I also tried with a * as seen below. I'm not too familiar with WMI. The query looks fine, does this suggest anything to you?

     

     

    Edit: didn't allow my image through.

     

    query was   "select * from Win32_OperatingSystem"

     

    Result was

     

    Number:0x80041010

    Facility: WMI

    Description: Invalid Class

    Re: WMIC/WMI Datasource against Domain Controller

    It does tend to suggest WMI is not working properly and may not be a Zenoss/wmic issue. Can you do the following:

    1) Run the same test locally on one of your member servers that are not having the WMIC issue. Does that query work there?

    2) Is this a Windows 2008 Server? If so can you try running wbemtest as Administrator (right click --> run as administrator)

    Re: WMIC/WMI Datasource against Domain Controller

    1) Fails on a member server as well. Wmic/Zenoss zenpacks work against this member server. Seems wbemtest isn't a good one for me - atleast not as configured.

     

    2) server 2003

     

    Curious

    Re: WMIC/WMI Datasource against Domain Controller

    Can you try replacing 'default\root' in the namespace field when you connect with "root\cimv2" and run those tests again? Sorry for not catching the name space difference earlier.

    Re: WMIC/WMI Datasource against Domain Controller

    Ok replaced namespace to root\cimv2 and wbemtest worked on both DC and member server. My fault, again not a wmi guy and saw the root - was thinking it defaulted to the top of the tree.

     

    So wbemtest is working on both. My firewall guys swore up and down all the ports were open but they were not. Just confirmed.

     

    Thanks dpetzel I owe you one.
