Until about 2:30 CDST on 3/18 I've used Sharepoint Designer to work on my OLSB site and all has operated flawlessly for years.  Since Thursday afternoon access to the site at all has been very sporadic with constant 401.1 errors usually resolved with multiple F5 renewing until the next access problem a few minutes later.  List use and/or customizing is almost impossible.

Sharepont Designer can't access any workflows or code pages with the constant error: "Your Web server does not appear to have any authentication methods enabled. The server has asked for user authentication, but did not send a WWW-Authentication header."

There seem to be some upgrades going on at OLSB but this is my livelihood and what, up until now, has been a very reliable service has turned into a real mess.  If these are known problems that are being worked on I'll be patient, but would appreciate a reply in any event.

OS is XPProSP3; MS Office and SharepointDesigner 2007SP2; IE7 and all Windows and Office updates are current; site is: co-actcentralcom.officelive.com

Thank you,
