Direct answer
Inventory remote support methods and their owners, verify which operators can reach each device, and test allowed and denied access without interrupting essential support.
Map support channels
Identify remote desktop, approved remote assistance products and third-party support access. Record their purpose, responsible team, authentication method and required network path. An installed tool does not by itself show who can use it or whether it is currently reachable.
Review access and configuration
Compare authorized operator groups and device assignments with the support roster. Microsoft notes that Remote Desktop access requires appropriate user permissions and supports Network Level Authentication. Apply the relevant vendor guidance separately to other support tools.
Reference: Microsoft: Allow Remote Desktop access.
Verify and maintain
Use dedicated allowed and denied test identities under an agreed window. Confirm that valid support still works, review audit records and remove obsolete access through the owning policy. Preserve an independent recovery method before restricting a device's only support path.
Example: a temporary vendor assignment
A vendor support group may have been added for a migration that has ended. Confirm its current purpose and expiry with the owner, then test removal on a representative device while an independent internal support path remains available. Recheck the management policy so the next refresh does not silently restore access.
Assessment limits
Remote support products have different security and network models. A selected access test does not cover every administrator, external route or compromised account.
Frequently asked questions
Does installing a support tool mean everyone can connect?
No. Check operator permissions, device assignment, authentication and network reachability.
Should old access be removed immediately?
Verify ownership and dependencies and preserve an approved recovery path before a change.
Does a blocked test prove all paths are blocked?
No. It establishes only the tested account and network path at that time.
