FIX SCCM Console Access Error 0x80070005 0x800706ba RPC Server is Unavailable
Fix SCCM Console Access Error 0x80070005 0x800706ba RPC Server is Unavailable. I started getting comments on How to Verify WMI Permissions Required for SCCM Console Access post back in June 2022.
David N commented on the SCCM console WMI permission post on 27th June that “the workaround (of setting RequireIntegrityActivationAuthenticationLevel = 1) did resolve the issue.” But Microsoft fixed this issue permanently now without any registry hack!
I have blogged about the error 0x800706ba RPC Server is Unavailable before – Fix ConfigMgr DP Issue RPC Server Is Unavailable Error Code 0x800706ba. The errors and fix discussed in this post are a bit different.
I have seen a note from Rashid Siddiqui on Twitter about a FIX from the Microsoft side – “Some customers may face issues with provider connectivity, Remote Control, and Content distribution after installing June security patches due to DCOM hardening changes.” More details are given below.
SCCM Console Access Issue because of DCOM hardening
Let’s check more details on the SCCM Console Access, Remote Control, and Content distribution Issues because of DCOM hardening. The Dcom Harding happened on the Windows side with June 2022 patches as mentioned above.
When you check the SmsAdminUI.log (SCCM logs for admin console) from the following location(s) depending on which device or server the console is installed.
- Remote Site Server – D:\Program Files\Microsoft Configuration Manager\AdminConsole\AdminUILog
- Remote Admin Console Server – C:\Program Files (x86)\Microsoft Endpoint Manager\AdminConsole\AdminUILog
The following table gives you more details on the issue and its impact on different components of SCCM. These components include SMS Provider, DP, Client, SCCM Admin Console, etc.
| Issue | Impacted SCCM Components/Tools | Error Message |
|---|---|---|
| Console fails to access the SMS Provider remotely under any user account | SCCM Admin Console | 0x80070005 – Access is Denied |

Workaround to FIX Errors Error 0x80070005 and 0x800706ba
The following are some workarounds shared by David N in the comments section of the WMI Permission post as mentioned above. I don’t recommend the workaround now because Microsoft shared a permanent solution for this issue.
DCom Hardening changes were required for CVE-2021-26414. Microsoft recommended that you verify if SCCM client or server applications that use DCOM or RPC work as expected with the hardening changes enabled. You can enable or disable the hardening changes for CVE-2021-26414 using the following registry settings.
| Registry Path | Value Name | Type | Disable – Enhancement | Enable – Enhancement |
|---|---|---|---|---|
| HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole\AppCompat | RequireIntegrityActivationAuthenticationLevel | dword | 1 (decimal value) | 0 (decimal value) |
