VSS 密码忘记了怎么办？清除Admin密码。

the secret is to hack the um.dat file to remove the Admin password       
                                                                         
from offset 80 the bytes are (all numbers are hex)                       
                                                                         
0:80 55 55 bc 7f 41 64 6d 69 6e 00 00 00 00 00 00 00                     
0:90 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00                     
0:a0 00 00 00 00 90 6e 00 00 a8 01 00 00 00 00 00 00                     
                                                                         
Just load the um.dat file into a hex editor and change the bytes from =  
offset 80 to exactly what is shown above. When the SourceSafe admin tool =
starts it believes that the admin password has never been set.           
                                                                         
the hex values above are taken from a 'virgin' um.dat file               
                                                                         
of course, you didn't get this from me....and ALWAYS backup first (just =
in case I'm wrong)
