This is the solution if you got this error message when trying to do Analyze and Repair some VSS database using does prompt command:
C:\>”C:\Program Files (x86)\Microsoft Visual SourceSafe\analyze.exe” -F -V3 -D “\\my_server\my_vss_database\data

Error was:

Database analysis in progress File ../data/status.dat is already open Cannot rebuild the database while Visual SourceSafe is being run. Make sure all users have exited SourceSafe and try again.

Solution

Make sure there are no users connected to the VSS database (running ssexp, ssadmin, etc), that users cannot connect to the database using the web service (they connect only for short times, so it’s hard to see them listed as logged in with ssadmin), and that VSS LAN Service is stopped (use net stop ssservice), as it may keep a connection open to the database.
