mbsacli.exe error?

Hi,

I have just used the MBSA command line tool mbsacli.exe to scan 170
different servers

I used the following command
mbsacli /target {servername} /n Password+IIS+SQL+OS /nai /nm >>c:\myscan7.txt

Of the 170 servers I scanned 5 produced errors:
one of them Result: Cannot deploy security metadata. (0x00000079)
four of them Result: Cannot deploy security metadata. (0x0000046a)

Can anyone enlighten me to what these error codes mean?

Thank you
Brendon
