一不小心将VSS 6 admin用户的密码忘记(再此证明我的粗心
)，Google了一番,找到以下信息
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)
有朋友看不懂，我用中文解释一下
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。
呵呵，看来不用担心。
发现一个不错的vss FAQ http://www.michaelis.net/SourceSafe/Faq.htm
