Attempting to run Google Workspace Password Sync (GSPS) on a Domain Controller and getting error 0x80070002 or 0x80070057?
Running app version 1.8.17.0?
If you have another network adapter on the server that doesn’t have internet access (local network connection), that could be the problem. Disable every network adapter except one with internet access.
Changing the network interface metric doesn’t always resolve this issue.
Google Password troubleshooting documentation (as of 2023-06-23) can be misleading regarding these errors as well, indicating File System Errors or Authentication problems.
Running the Google made support tool didn’t identify this as an issue.
