We are having a situation with our Windows SBS 2003 server dropping packets. The machine is setup as a NAT device for our network and handles DHCP, DNS, Exchange, etc. We have 2 T1's bound together on the outside and we consistently use a megabit or more of bandwidth throughout the day. Our stock feeds will occassionally drop as will various web pages. Is there any way to increase the NAT buffer or some other config item I need to change? Thanks in advance, because this is really frustrating.
