we have a standardproxy that also handels the DNS requests for connections to the internet.After configuration the AD Sync Utility tries to contact https://cloud.sophos.com but cannot get a DNS resolution for this URL.
I have not found any option to configure a proxyserver inside the utility and it apparently does not use the one set as system default.
Can somebody please give me a hint how to solve the problem ang get the AD Sync working.
The problem could also be that the Active Directory Sync tool runs as a service account and not a user account. I had a customer with a similar problem.
I ran this command - netsh winhttp import proxy source =ie. This the same command that an Endpoint may require. This still didn't fix the problem until I changed the service account to run as a user. If you use a standard domain user than the account will need these permissions.
As a quick test you could use a Domain Admin account. Every time you change the service account the Active Directory Sync tool will need to be reconfigured
