Remote Assistance fails on Domain - Windows 7 to Windows 7
I can offer RA to some machines but not all. Our computers are running Windows 7 Pro 32-Bit on a Windows Server 2008 domain. I created Remote Assistance GPO to enable the feature needed on network. User Account Control: Allow UIAccess applications to prompt for elevation without using the secure desktop - ENABLED Offer Remote Assistance - ENABLED (Added our group to Helpers list) Solicited Remote Assistance - DISABLED Confirmed HKLM>Software>Microsoft>OLE, EnableDCOM = Y I even installed RA on the domain controller. I can access the desktop's C:\ from the network so I can access the targeted computer but I get the following error from RA: I checked the Default Properties on the targeted computer and confirmed "Default Authentication Level - Connect" and "Default Impersonation Level - Identify". Enable Distributed COM on this Computer is checked. I check EventViewer and get the following error: Log Name: System Source: Microsoft-Windows-DistributedCOM Date: 3/15/2013 2:32:51 PM Event ID: 10006 Task Category: None Level: Error Keywords: Classic User: N/A Computer: ComputerName.doamin Description: DCOM got error "2147746132" from the computer 10.x.x.x when attempting to activate the server: {833E4010-AFF7-4AC3-AAC2-9F24C1457BCE} Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Microsoft-Windows-DistributedCOM" Guid="{1B562E86-B7AA-4131-BADC-B6F3A001407E}" EventSourceName="DCOM" /> <EventID Qualifiers="49152">10006</EventID> <Version>0</Version> <Level>2</Level> <Task>0</Task> <Opcode>0</Opcode> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2013-03-15T19:32:51.000000000Z" /> <EventRecordID>17724</EventRecordID> <Correlation /> <Execution ProcessID="0" ThreadID="0" /> <Channel>System</Channel> <Computer>PCName.domain</Computer> <Security /> </System> <EventData> <Data Name="param1">2147746132</Data> <Data Name="param2">10.x.x.x</Data> <Data Name="param3">{833E4010-AFF7-4AC3-AAC2-9F24C1457BCE}</Data> </EventData> </Event> Error 3/15/2013 2:32:51 PM DistributedCOM 10006 None I check the EventVwr on Target Computer and I see this error: The application-specific permission settings do not grant Remote Activation permission for the COM Server application with CLSID {3C3A70A7-A468-49B9-8ADA-28E11FCCAD5D} and APPID {F8FD03A6-DDD9-4C1B-84EE-58159476A0D7} to the user Domain\UserID SID (S-1-5-21-2372432400-2791315748-1353314665-5232) from address 10.x.x.x. This security permission can be modified using the Component Services administrative tool. If anyone can help me I would greatly appreciate it. I also hope this is in the correct Forum Category.

I decided to add usernames to the helpers list and the Security Filtering on the GPO is empty as I want it to apply to everything in the OU. The OU has all the desktop/laptop computer accounts.

RESOLVED!! I figured it out. I ran Gpresult /scope computer on my machine and one of the machines it was failing to connect to. I noticed my Remote Assistance Policy was failing to be applied even after running gpupdate /sync /boot /force. I enforced the policy and still not working. I left the Security filtering blank because I didnt want it to be filtered. That was my error. I filtered it to "Authenticated Users" and ran the gpupdate again. This applied the remote assistance to my and the target machine. Tested the RA, connected w/o issue.
