Recover SourceSafe Password

Many times my customers are asking for possibility to recover VSS Admin password, most of the time they have old VSS server nobody touch it for quite some time and now they want to search for some code but nobody can remember Admin password.

Recover the password is required a new user file and rights file needs to be created. Doing this removes all users except GUEST and ADMIN, which are reset to SourceSafe defaults.
All other users must be recreated. In addition, all rights will be lost and therefore will have to be recreated.
Before you start to recover make sure to copy USERS.TXT file that contain a list of current users, you will need it when you create users after recovery

VSS_Rec_01  VSS_Rec_02

Create a local user “Admin” with Administrator privilege on vss host and then Logon with “Admin” account

Method 3:
