Windows 7 Event Viewer Error "Failed to connect to the driver: (-2147024894)"

It seems as if the Dropbox service may be trying to start too soon as, after the initial error, Windows seems to be able to correct the problem and everything works correctly. This is a very recent happening and I cannot relate the change to any system changes. Is there anything I can do to stop the error - if I didn't regularly check the Event Viewer I would be none the wiser so perhaps I'm being too sensitive.
Thanks.
Hi everyone!
Sorry for the delay here -- I usually hang out on the client builds forum and missed this.
This error is expected and harmless. We are optimistically checking for features currently in development and logging an error when we don't find them enabled. We shouldn't be logging it as an error, however, perhaps as an Informational-level event and I'll make sure we clean this up in a future release.
If you're suspicious that this has been causing instability -- this hasn't really changed since last summer so it's probably not the droids you are looking for (combined with the fact that the error is indicative of things not happening, rather than things happening that are potentially destabilizing).

- Hi all,First: Many apologies for the delay in jumping in here, I wanted to make sure I had a concrete update for you all.So, for context: What is Dbxsvc? :I've added a section to the help center article: https://help.dropbox.com/desktop-web/smart-sync (I say section, it's more of a note at the bottom under the driver FAQ).The file dbxsvc.exe is a file that we use to install the Smart Sync driver. Should you not be a business user, or not have Smart Sync, then this file will never start operating. It is, however, created at install for all users so if you are not a Smart Sync this file will still appear there.I see we have a number of pretty interesting, creative suggestions on how to disable, coupled with queries if it's safe to disable it. I'm of course not going to endorse a process that disables part of our software, should a feature or functionality cause user pain then we would want to know. Fixability and timeframes can vary depending on the in-depth technical nature of the problem.Should you decide to disable it with one of the solutions here, it will prevent the smart sync feature from working in some cases. We need the service to update the driver, as well as to establish new driver<->client connections. This is the services current functionality. Additional functionality could be added over time. My main concern around anyone disabling it is that in the future you may need this process, Smart Sync won't work correctly, you can reach out to support but this custom change you've made will be hard for us to diagnose as the root cause of whatever issue you experience.Why is it failing to connect / what's going wrong?:It should be failing to connect. This is by design, the actual issue you’re facing is due to the frequency we're writing to the logs. To address any concerns around error with the application, these errors are in no way indicative of a software issue and do not point to any issues with backing up you data. Because it fails to connect, Windows treats this as a trigger to write to the log. Your data is safe, this process is just used to install a driver. As covered in the above section we expect it to do what you are seeing.With that in mind, we understand that some of you do wish to see this behaviour.Why aren't we fixing this?:We are, we take our user feedback very seriously and we have spent many hours working on this. As fixes have many dependencies, and are just one components of a version release, I'm always reluctant to jump onto a thread and give a firm release date for a fix as these are regularly subject to change.You may have noticed that we took the original connection attempt frequency down from every 1 second to every minute. This was an improvement we took onboard based on the feedback you've supplied here and also via other channels. Our new release, 31.3.15, has further improved this, the process will run 3 times daily. This should reduce the errors written to the logs and not clutter the report.The new beta version is the first to include a fix:

Hi Mark,
Unfortunately the resolution is out of the user's hands but we are told that the Dropbox development team are working to find a solution. Fortunately, at least formost of us, we are still able to use Dropbox as normal.

Hi,
the error is still present with the latest DB version (16.4.30). I did some research for the error code -2147024894, which if converted to a 32 bit hexadecimal value results to 0x80070002. I found a registry for those values at Symantec, and it revealed it to be of type "Win32 Error Codes for ADSI". Additional Research at Microsofts Developer Network showed a bit more details: Looks like it is the error code for a failed LDAP request (LDAP_NO_SUCH_OBJECT). So the questions seems to be: Why does DB do LDAP (or Active Directory with Windows) requests? And will the observed error within Event Viewer only happen with Windows PCs that are not members of an Active Directory?
I did some further investigation and figured out that the error was safely reproducible every time the "DbxSvc" service starts. Hence inside service manager I stopped this service and started Wireshark and SysInternal's Process Monitor in order to see what happens after I have started the service again (this way provoking the error to happen once more).
These are the results: During service start no network activity could be observed. All file and registy access of the process named "DbxSvc.exe" didn't reveal any hints that something went wrong (no results more critical (but normal) than "NAME NOT FOUND" or "BUFFER OVERFLOW" with registy access or "FILE LOCKED WITH ONLY READERS" with file access).
Only the last registry access asks for the value of "HKLM\SOFTWARE\Microsoft\Windows\Windows Error Reporting\WMR\Disable", probably to check if errors should be reported to Microsoft.
Hence, it's still a mystery why this error happens. This thread says, that this service isn't even needed to use DB:
"You noted sync still appears to work correctly without this service however should you encounter any sync issues with the service removed it will limit our ability to resolve the issue."
Btw: The OP reported about ESENT messages he believes cause a recovery from the error state. With my PC I also see these ESENT messages but they happen at other times than the DbxSvc.exe error - hence, I believe they are independent from each other.
