I'm accessing these groups thru the MS web interface at:
http://www.microsoft.com/communities...&lang=en&cr=US
....and as I'm trying to navigate the web pages to previous discussions, I'm
getting a whole lot of "Service Temporarily Unavailable" web page errors.

Is this a problem with firewall-type iissues, or is there something up with
MS's web interface? I never used to get these (and come to think on it a bit
more, I think I've been getting these errors from home too, so that should
rule out any local corporate firewall issues.)
