I am publishing Exchange Client Access with ISA 2006. I installed ISA Server 2006 standard edition but ISA services were not started and got the following errors in the event log.The ISA Server Standard Edition cannot run. Either the server is using more than 4 processors, or it is configured to use the Active Directory service. Use the source location 100.305.5.0.5723.493 to report the failure. Contact Microsoft (R) Corporation for more information. I installed the hotifx 932370 and 943462 andchanged the /numprocs=4 in c:\boot.ini but it doesn't work.I would really appreciate if anyone help me to resolve this.Thanks and Regards,Nitinnitin_pangerkar
