I am running sbs2003, single NIC without ISA and a Netgear DG834G firewall.
I think that some of the users on my network are logging into their online email yahoo, gmail and hotmail etc. via Internet Explorer and attaching company files to email out because usb is restricted on the computers. They are not emailing files out via Exchange but via Internet Explorer.
Is there a way to log/check which files have been sent out or is there a way to block users being able to send files out ia internet explorer with the setup i have at the moment?
I know i can block sites using the firewall but is there a firewall port i can block so that i can stop this happenning.
The files are mainly .DOC and .XLS files but i still want to be able to send them out via Exchange email (Outlook)
PLEASE HELP ME!!!
