ISA server 2004 - Single NIC config In a single adapter configuration of ISA server 2004 I am unable to connect to Internet on the ISA box nor can clients access internet. Following are the error msg that I get: ISA server error message: ISA Server detected routes through adapter "Local Area Connection 2" that do not correlate with the Network Element this adapter belongs to. The address ranges in conflict are: 203.xxx.xxx.1-203.xxx.xxx.1;203.xxx.xxx.242-203.xxx.xxx.242;203.xxx.xxx.255-203.xxx.xxx.255;. Fix the Network Element and/or the Routing Table to make these ranges consistent -- they should be in both or in neither.
