SOLVED ---> Unable to connect to WMI on remote machine "computername", error = 0x800706ba

[Corey Preman]

Server 2008R2
SCCM 2007 SP2 (4.00.6487.2000)

I am getting the following errors, no packages are being sent to the clients:

CCM.log errors:
CWmi::Connect(): ConnectServer(Namespace) failed. - 0x800706ba
---> Unable to connect to WMI on remote machine "computername", error = 0x800706ba.
---> WNetAddConnection2 failed (LOGON32_LOGON_NEW_CREDENTIALS) using account sonesta\xxxxxx-install (00000035)
---> WNetAddConnection2 failed (LOGON32_LOGON_NEW_CREDENTIALS) using account sonesta\xxxxxx-install (00000035)

The install folder/files are not getting pushed to the CCM\Cache on the client.
I have configured Client Push Installation Properties
I have Firewall turned off




MS cannot figure out what is wrong.

Please HELP!!!! I am under a deadline to push a new package and SCCM is not pushing anything.

Turning off firewall will not help. You need to check if there are DNS issues within the network. Did you try to resolve any computer names ?. Check the below troubleshooting steps :-

Unable to connect to WMI on remote machine, error = 0x800706ba.

1) Ensure you have opened the below listed ports on the firewall.

2) Ensure File And Printer Sharing and WMI is opened on the clients Firewall to allow the client push to work correctly. Check this link - http://prajwaldesai.com/configuring-firewall-settings-for-configuration-manager-2012-r2/

3) Error 0x800706ba = The RPC server is unavailable. Can you connect to the remote machine using explorer (admin$), regedit and WMI (wbemtest)?

sometimes the security software such as antivirus also is the reason for this issue - http://prajwaldesai.com/community/t...o-wmi-on-remote-machine-error-0x800706ba.436/
