    @Tom - no problem!

    On the other had i am unsure why giving unauthenticated access to office.microsoft.com works - its not as if the requests are for this website they can be for any website - also it can't be an IE problem as it also happens in firefox or chome!

    Put in the ACL the other day but it seems as though something on the website comes from another domain name (not .microsoft.com or .msecnd.net) as the webpage loads but its still asking for credentials for the proxy and we are still being redirected to this website.

    This doesn't seem to be an ntlm issue - as we have found someone with an ident setup suffering. So, we can rule that out. We're still trying to replicate it in the lab.

    Early last week I had a complaint from the high school stating that the problem had cropped back up (what was odd is that the frequency of occurrences went way down). So, I tried out my last idea and it seems to have held through four full school days. I left the NTLM bypass tweak in place (knew I would be adding sites to the list for other various problems), and added another to bypass the upstream proxy for those two domains. Config looks something like this....

    acl bypassNTLM dstdomain "/etc/squid/bypassauth-sites.squid"
    acl BypassCache_peer dstdomain "/etc/squid/bypasscache_peer-sites.squid"
    acl NTLMUsers proxy_auth REQUIRED

    http_access allow all bypassNTLM
    http_access allow all NTLMUsers

    cache_peer YOURCACHEPEER.com parent 8080 0 no-query proxy-only
    always_direct allow BypassCache_peer
    never_direct allow all
    The "bypassauth-sites.squid" and "bypasscache_peer-sites.squid" files contain...

    .microsoft.com
    .msecnd.net
    I've been constantly calling the media paras at each build asking they had seen this issue repeat itself since I implemented this last change and all have said they haven't. I'm not declaring victory or anything, but this band-aid seems to be holding.

    Good luck and keep us posted.

    @Glenda: Any new developments? We haven't had any recurrences since my last post, but I'm still wondering what the underlying problem is.

    I have just added this in and have asked teachers to report back next week if this has worked.

    Tom are you any nearing to finding out why this is happening?
