ISA 2006 LIVE MESSENGER & YAHOO NOT WORKING?

i think ISA is internet server administator?-anyhow, if ur able to go the route, looks like u have to update/upgrade to 2008-9 live messenger, n yahoo 2008. Do NOT-DO NOT update to IE8, 2 many problems, n not compatable with several programs. i did, and got rid of it. the newer version of windows live messenger i think is great, a live messenger is similar to yahoo messenger. i like it, n keeping it. i really hope this helps. alos if u want-get a book on (not to offend) internet for dummies(again-not to offend), IDG does the book. it should help. i,m reading my 3rd one.
