VSS Admin 清除密码

[参阅链接]http://www.cnblogs.com/Zealot/archive/2004/09/18/44309.html

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)

如果忘记了密码，打开你vss数据库所在的文件夹，打开data目录，
找到um.dat文件，用hex编辑器打开编辑它，从offset 80的55 55 开始
将值改为如上文所述的样子，然后保存，这样um.dat文件就回到了
初始状态(virgin ?  :))，然后打开vss admin,用admin用户登录，不需要
密码了。
