Not to panic; if ISA services fail to start, the server is more locked out than if ISA was running. This message indicates that a server publishing rule is using a client address set exclusion that can't be found. You can trace this out two ways: 1. go through the ISA MMC and walk the server pub rule and verify that all of them use data sets that actually exist in ISA policy elements, and that those policy elements are ok 2. go into the registry to where the error message indicates and see what GUID is referenced for the ClientSetExcluded this GUID should be found in SOFTWARE\Microsoft\Fpc\Arrays\{61EFC420-9150-47E4-ADF6-768E993D302C}\PolicyE lements\Client-Sets\{GUID} each IP set in that client set will have its own GUID Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/authors/harrison/ Read the books! ----- Original Message ----- From: "Larissa Aigner" <laigner@xxxxxxxxx> To: "[ISAserver.org Discussion List]" <isalist@xxxxxxxxxxxxx> Sent: Tuesday, January 15, 2002 19:58 Subject: [isalist] An error occurred while reading configuration information http://www.ISAserver.org I just got the below alert.
