شباب حصلت المشكلة وحصلت الحل بس يبي ترجمة ياريت احد يقولنا ايش الحل ؟؟؟
If you find the connection to the Internet stops after it has been functional for a period of time, perform the following steps to confirm the problem:
Open a command prompt and type ipconfig /all and press ENTER
If you see that the IP address for your PPP connection is 0.0.0.0, this indicates that the ISA Server 2000 firewall was not able to renew its IP address because the cable company is using an incompatible DHCP method.
Close the command prompt window.
If you encounter this problem, you have two choices:
Put a cable router in front of the ISA Server firewall and use an Ethernet connection on the external interface of the ISA Server 2000 firewall computer. Configure the external interface of the ISA Server 2000 firewall to use the internal IP address of the cable router as its default gateway
