Windows agents implementation - c++

One creates a Windows agent by calling CreateService with one of the following two parameters: SERVICE_USER_OWN_PROCESS or SERVICE_USER_SHARE_PROCESS. When SERVICE_USER_OWN_PROCESS is used, the agent will start with the next login and it will have a name like < service_name>_< some session ID>. Example of Windows 10 Microsoft agents: MessagingService_ba3d3c, PrintWorkflowUserSvc_ba3d3c or DevicesFlowUserSvc_ba3d3c (call sc query type=userservice to see the active ones) - in this case, the is 0xba3d3c, while the Logon Session is 0xba1a53 (close, but not enough) (seen with Process explorer).
My questions are:
Can I start the agent immediately after installation without logout? It would help with the installer that asks for reboot now.
What is this mysterious "session ID" ? It would help with the testing, to avoid enumeration and guessing.

Microsoft Dynamics NAV instance running after windows restart but not responding

I've got issue with Microsoft Dynamics NAV instance.
We're restarting Windows server each night (I know that we probably shouldn't do it, but this is a separated topic and not the point of this question).
After windows server starts, SQL and Dynamics Nav instances are starting. Sometimes (1-2 times per month) Dynamics NAV instance is marked as 'Running', but actually doesn't respond (Web services are not working, RTC client cannot connect to this instance etc.). We have to restart Dynamics Nav instance manually once again in order to get it working correctly.
Did anyone have similar problems? We were looking into Windows Logs, but couldn't find anything interesting..
We also wonder if we shouldn't manage start of the services (SQL server, Dynamics Nav instances etc.) manually somehow instead of depending on the automatic start of everything after windows restart.
Update:
There is actually one error in the Windows Event Log which occures ONLY in days when Dynamics Nav instance is not started corretly:
Server instance: XXXX

I'd suggest Delayed Start to help alleviate missing dependencies such as certificates OCSP validation without internet, etc. There should be Windows Logs saying the The service has completed configuration and is ready.
Service Auto-restart actions might help catch unexpected errors, but as it's Running I'm not sure it'll exactly apply to your situation.
The service tier should not be restarted nightly, as you've pointed out :). It might be easier to solve that issue, but I can't suggest anything without more information.
Also, which version of Dynamics NAV/Business Central?

CoRegisterClassObject returns error (session 0?)

A customer is running one of our programs, usually run as a service, as an application. The customer is getting the following error on CoRegisterClassObject():
The class is configured to run as a security id different from the caller.
It looks like some type of session 0 error, but why should CoRegisterClassObject() care about session 0? COM should allow both services (session 0) and apps (session > 0) and not care what registers what, shouldn't it?
Also, I don't like the fact that it's not in the list of errors returnable by CoRegisterClassObject(), as per the Microsoft doc webpage.
The error code in question is CO_E_WRONG_SERVER_IDENTITY (0x80004015).
Per this page:
COM security frequently asked questions
Q6 Why does CoRegisterClassObject return CO_E_WRONG_SERVER_IDENTITY? When launching my ATL 1.1 server service as an .exe file, I receive CO_E_WRONG_SERVER_IDENTITY from CoRegisterClassObject. (The class is configured to run as a security ID different from the caller.) This seems to occur whether I skip the CoInitializeSecurity or not. It fails running as a service or as an .exe file.
A. Many services are debugged by running them as console applications in the interactive user identity. Because the service is already registered to run in a different identity (configurable by the Services control panel applet), OLE fails the CoRegisterClassObject and RunningObjectTable::Register(ROTFLAGS_ALLOWANYCLIENT) calls by returning CO_E_WRONG_SERVER_IDENTITY to enforce security and to prevent malicious servers from spoofing the server. To debug by running in the interactive user's identity, make the following changes in the server's registry entries to prevent these failures:
• To prevent CoRegisterClassObject failure, remove the following named value:
[HKEY_CLASSES_ROOT\APPID\{0bf52b15-8cab-11cf-8572-00aa00c006cf}]
"LocalService"="HelloOleServerService"
• To prevent a IRunningObjectTable::Register(ROTFLAGS_ALLOWANYCLIENT) failure, follow these steps:
Remove the following named value:
[HKEY_CLASSES_ROOT\APPID\{0bf52b15-8cab-11cf-8572-00aa00c006cf}]
"LocalService"="HelloOleServerService"
Then add the following named value:
[HKEY_CLASSES_ROOT\APPID\{0bf52b15-8cab-11cf-8572-00aa00c006cf}]
"RunAs"="Interactive User"
You muist restore the modified registry entries after debugging.
I am assuming you would have to replace {0bf52b15-8cab-11cf-8572-00aa00c006cf} with your COM object's actual CLSID instead.

Thanks for posting here.
To resolve this issue, review the AD group membership for any circular references and remove them. If the circular reference is not obvious, the script below can list the nested members of a particular group.
NOTE Use Active Directory Users and Computers to determine the top most group of the group causing issues.
dsquery group -name "Group_VMMSSU" | dsget group -members -expand
I hope you have followed these steps before installing SCVMM
High Level Deployment Process:
In AD, create the following accounts and groups, according to your naming convention:
•DOMAIN\scvmmsvc SCVMM Service Account account
•DOMAIN\scvmmadmin SCVMM RunAs account for managing hosts
•DOMAIN\sqlsvc SQL service account
•DOMAIN\SCVMMAdmins SCVMM Administrators security group
Add the “scvmmsvc” and “scvmmadmin” account to the “SCVMMAdmins” global group.
Add the domain user accounts for yourself and your team to the SCVMMAdmins group.
I suggest you to check this link for more details.

I had this error and couldn't find an updated answer to the problem.
In my case, I have SCVMM (server AND console) installed on the same machine (i guess this is pretty normal for a first time installation).
I had seen the system working, then I installed all updates offered from Windows Update. After reboot, my service "System Center Virtual Machine Manager" could not start.
Solution was to look in control panel: "Programs and Features". Clicking "installed updates" there was an entry for System Center Console.
This was a rollup 10.
I uninstalled this, now the service is able to start, and I can log on.
Hope this helps someone.
This KB article from Microsoft addresses the issue- https://support.microsoft.com/en-us/kb/3045931
To resolve this issue, complete the update rollup installation by installing the VMM server update package in addition to the console update. Both the VMM server and VMM Admin Console updates must be at compatible version levels. This will typically be the same update rollup level. For example, a VMM Admin Console should be at the VMM UR5 level if the server is also at UR5.  
In some instances, there may not be a comparable update for a component. In that case, the component should be updated to the most recent applicable update. For example, if the VMM server is updated to a post-UR5 hotfix, but there is no corresponding hotfix for the VMM Admin Console, the VMM Admin Console should be updated to UR5.
In my case update rollup 11 was the cause for the break. Going in to Programs and Features -> Installed Updates, I noticed that Update rollup 11 for the admin console had installed successfully but Update rollup 11 for the VMM service had failed.
I manually installed the failed update (in my case http://download.microsoft.com/download/7/5/1/7515E3DB-1B43-4E7F-8774-A877CCEAA96E/kb3184831_vmmserver_amd64.msp) and now VMM service is able to start and stay started.

error 5 when starting a service

i created a windows service in c++ and when i try start the service i get the message error 5: access denied.
my user account is set to admin and i even tried using the default admin account on the computer and it still doesn't work.
i can install/uninstall the service through the cmd without problems but i can't start the service
the code isn't the problem here its the user account. any suggestions on how to fix this?
"Running a service" is not simply "starting a program on my desktop". It does not necessarily run as "you".
The service is detached from any desktops and it actually ignores your user account. The service will have its own account/password configuration stored in the OS and when you run it, you only order it to start up. It will startup on its own user account. If you have put your .exe/.dll files in some protected folder, and if you have not configured neither the accessrights to that files nor user-pass for the service, then there's great odds that the service tries to run at default service user account like 'LocalService' or 'NetworkService' and that it simply cannot touch the files.
If you installed the service properly, go to ControlPanel - AdministrativeTools - Services, find your service and check the (if I remember well) second tab and verify that the username presented here has access to the files that are tried to be loaded and run. If the username is wrong, correct it. If you don't care about the username, then just peek that name and set accessrights on the folder and/or files such that at least both "read directry contents" and "read" and "execute" are available for that-username-the-service-tries-to-run-as.

Build never starts on TFS2012

I'm attempting to set up some build controllers and agents in our TFS infrastructure. Our TFS server is setup as a build controller, and I have a few build agents set up as well.
When I queue a new build on my system, all appears to be well. No error messages appear, and the build appears in the queue on my system. However, that's all that ever happens. When I go to the page for the build in Visual Studio, it states it's been "Running for 0 seconds". Looking at the admin console on our TFS server, the controller states it's "Ready", but nothing more. All the agents are similarly listed as 'Ready'.
I'm not aware of any logs I can use to diagnose this issue. I've set the Logging Verbosity to 'Diagnostic', but options in the Diagnostics dropdown are greyed out. The activity is completely blank, as well.
Looking in the database on the build controller, the dbo.tbl_BuildController table does list the build. What I find odd, though, is the StartTime is NULL. If I stop the build in VS, the start time and the end time are set to the same thing in the database.
So, I know that the build is registering with the build controller, and that there's not a communication issue; the build just never starts, and never give an error. How can I resolve this? (or, at least get an error that I can chase down).
EDIT: The issue appears to be related to the TFS server. Here's what I uncovered in the event log:

I would start looking in the Event Log.
Control Panel -> Administrative Tools
Event Viewer
I am assuming that there will be some sort or error appearing in there. If your build agents are on a different machine, make sure you look in the event log there too.
Update from original posters comments
There was an exception in the Event Log which pointed us to here: TFS2012 Build Service offline
Go check the security settings of the user that is used for the build service properties. I've had almost the same issue and it was because I changed some security settings for that specific user where he suddenly could not build anymore.
To find the user:
Go to your TFS server
Open Team Foundation Server Administration Console
Open Build Configuration
Open Properties of the Build Service
This worked for me, password of the user account which was used to access TFS hosted on different Server expired.
Password reset fixed it for me.
The build controller and agent must run the same version of Team Foundation Build.
(Buid Service version is something like v4.0 or v4.1 and it is different from tfs product version which is some thing like 11.0.50727.1)
So, if the build Agent and controller are deployed in different machines, check the build service version on both machines. it must be the same.
TFS prevents to assign a build agent to a build controller with different build service version. However, you are allowed to upgrade one of the build machines to a different version (for example visual studio update 2) without detaching the controller and agent
in some cases the build service version stay unchanged (for example inspite of upgrading to update 2 the version stay v4.0)
in this situation if you want to apply the new version of build service
in tfs 2012 or 2013 to check the build service version:
Go to Build Machine
Open Team Foundation Server Administration Console
Open Build Configuration
Open Build Service properties (click on the properties link next to the unregister
link)
"Listen for build agent communication on" text box
to apply change of the build service version
stop the service
Click the "Change" button
set a different port number
reset the previous port number
immediately the build service version will change from v4.0 to v4.1
