ISA Security

By raju.reddy009 ·

i have one windows 2003 server (AD) and one ISA in windows 2003 server.the AD is primary dns server but i make the ISA server as secondary DNS server and in that i configured DNS forwarder point out to my ISP gateway.

this setup running good but now some un identify traffice is runing in my client machines in my monitoring i found that unidentify and external IP also trying to connect my ISA server.I did't allow any external connections, But now i can't browse internet from ISA server as well as client machines too.

i suspect it might be problem some times from ISP but today totally i can't browse internet , but i wonder about one thing when i unplugged the internet connection from ISA and plugged in my laptop i am getting internet and every thing, if i again plugged it into ISA server it works 5 to 10 min after that same problem though i can ping my ISP DNS and second DNS servers too while connecting ISA server.

Pls help me if it is not understand to you just assume i have ISA server with DNS forwarder, i suspect some unidentify ip traffice in my cleit machines , now i can't browse internet, before 10day i got one alert in ISA that IP spoofing occured, what is this idon't have any idea pls help me
