A PRACTICAL STARTING POINT
Make an on-site visit useful
For an office or shared building, establish who can provide access to network equipment and approve work. Note reception procedures, access windows, and any coordination needed with building management or an existing IT provider.
Keep remote work focused
Account configuration, workflow reviews, and application work may be handled remotely when suitable access is available. Describe the problem before sharing credentials; we will agree on an appropriate access method if it is needed.
