ISA Firewall Lockout, Ceases internet traffic

Hi Experts,

I have an intermitant issue with our firewall that ceases internet traffic. I can RDP into my firewall but cant find anything in the logs.

when I check my External NIC it is not sending or recieving any packets. if I try to disable/enable the nic that doesnt work either.

then I try to restart my ISA services through services mmc but it gets stuck at the windows firewall and takes about 20 mins to stop that service but still after that I cannot enable my nic back. this is the time I need to restart my server and then everything starts running, internet is back.

I understand it wont be an easy fix and some monitoring needs to be done but I need ideas on how to approach this.

it only happens once in 2 weeks to 4 weeks.
