Re: Removing Local Admin Accounts - What do you think?

[Rob Thompson <my.security.lists () gmail com>]

I wanted to thank every one that responded to the e-mail that I sent out 
previously (below).  I had intended on writing back my 2 cents on the 
whole thing and acknowledge receipt of the responses, a while ago.  I 
got wrapped up and haven't really been able to get to too much else... 
I didn't mean to be rude.

Anywho - I think that it is a bad idea to remove the Local Admin acct. 
With the account gone, the only thing you are really doing is inhibiting 
the functionality of your IT department.

If someone is going to do something malicious to the machine, they are 
going to do it whether that account is there or not.

Again, thank you very much to every one that responded.  I really do 
appreciate your time.
