Two solutions:
1. using eval
2. using IFS, which fpmurphy also demonstrated

Code:
#! /bin/sh

LINE="CLIENT:0,3,6,9,12,15,18,21:/home/erm/user/CLIENT/PARM/unix_servers.txt:/home/erm/user/CLIENT/PARM/nt_servers.txt:/home/erm/user/CLIENT/PARM/CLIENT_url.txt:/home/erm/user/COACH/PARM/ping_serv_list.txt:/home/erm/user/COACH/PARM/pass.txt"

#
# solution 1 - two passes using eval
#
eval `echo $LINE | awk -F: '{printf("account=\"%s\";schedule=\"%s\";unixlist=\"%s\";ntlist=\"%s\";urllist=\"%s\";pinglist=\"%s\";ntpassfile=\"%s\";",$1,$2,$3,$4,$5,$6,$7)}'`
echo "SOLUTION-1:"
echo "account=$account"
echo "schedule=$schedule"
echo "unixlist=$unixlist"
echo "ntlist=$ntlist"
echo "urllist=$urllist"
echo "pinglist=$pinglist"
echo "ntpassfile=$ntpassfile"

#
# solution 2 - set IFS to be colon to help filtering
#
IFS_original=$IFS
IFS=":"
set -- $LINE
echo "SOLUTION-2:"
echo "account=$1"
echo "schedule=$2"
echo "unixlist=$3"
echo "ntlist=$4"
echo "urllist=$5"
echo "pinglist=$6"
echo "ntpassfile=$7"
IFS=$IFS_original
