1) If the workstations are joined to the domain, the default security settings place 'yourdomain\Domain Admins' as members of the local Administrators group. With that kind of access, it's very simple to grab the hashes of the local accounts and crack them. 2) Group Policy can operate through the computer's account to effect changes - this is a definite way to make changes to many settings on the machine. I suggest installing a syslog client on the workstations in question that casts eventlog entries to a machine under your control and turning up the audit policy to maximum. The client I'm familiar with is the SNARE client from www.intersectalliance.com - it works really well. However, if you can't trust your admins, fire them.

It's a catch 22 situation and I need to make our Windows Xp workstations appropriately secure. Secure from rogue Helpdesk personnel as well as network admins. The HR guys are complaining that their 'offer' letters to prospective employees and some of the CVs that they recieve are finding their way into unwanted hands. I suspect both HR application vulnerability, for which I am undertaking some vulnerability analysis but I also need to protect the PCs that belong to Dept. of HR employees from rogue IT guys. Here are the basics of what I intend to do: 1. Advise all HR users to shutdown their PC before they leave for the day. 2. Change all Local Admin passwords so that even IT helpdesk/other doesn't know them. 3. Advise HR guys to assign passwords to their excel/word files. 3. Do not create shares off c drive giving 'everyone' access. But...because they are all connected to Windows 2003 domain, I still risk someone from domain admin group to be able to start C$/D$ share and browse into their c: drive, what should I do? Also, it's easy to crack open xls/doc passwords, what else can be done? Alternatively, Is there an auditing on PC that can be enabled to track/log incoming connections to C$ and pop up and alert whenever someone tries it out from a remote machine. Pls advise!!
