Product: Internet Security and Acceleration Server
Event ID: 21113
Source: Microsoft Firewall
Version: 4.0.3443.594
Component: ISA Server Services
Message: There is no network adapter related to network ‘%1’. Network Load Balancing cannot be configured properly, and will be stopped on this server.
   
Explanation
The computer must have a network adapter that is associated with the network and has static IP address configured on it. Also, if the computer is running on Windows Server™ 2003 without any service packs installed (SP1 or later), the network adapter must not be the network adapter used for intra-array communication.
The Firewall service cannot find a suitable network adapter for one of the following reasons:
There is no adapter with an IP address in the range of the NLB-enabled network.The IP configured on the adapter is in the range of the NLB-enabled networks but the adapter is DHCP-enabled.There is no additional network adapter for intra-array communication (on Windows Server 2003 computers without Service Pack 1 installed).There are IP conflicts on one of the network adapters.
   
User Action
Change the network ranges of the NLB-enabled network so that they contain all the IP addresses of a network adapter which is not DHCP-enabled.Add an additional network adapter for intra-array communication.Check that the Virtual IP (VIP) you selected for the NLB-enabled network is not also configured as a Dedicated IP (DIP) of other computers in the subnet.
