Companyweb Problems on SBS 2003

After installing the latest batch of Windows updates, including an update for ISA 2004, I am unable to open the Companyweb intranet site on the SBS 2003 server with IE 7. It prompts for logon and password but none work, not even Admins credentials. This only happens on the SBS box, all other workstations and servers can bring it up as normal. If I use Firefox, I can logon with Admin credentials. I have tried browsing directly through IIS 6.0, with same result; I get the HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials. Internet Information Services (IIS).

Any help will be appreciated.

OK.  With a little help from a friend, Kirk Miller, the problem has been resolved.  Uninstall IE 7 update KB963027, reboot and I was back to normal.

Thanks for your help pqer.

You may want to run the "Configure E-mail and Internet Connection Wizard" again and igore all of the settings except for the firewall.  I've found that repairs the rules in ISA on an SBS server if they get hosed.

Thanks for the reply.  What do you mean exactly by "igore all of the settings except for the firewall."

Thanks,

When you launch the "Configure E-mail and Internet Connection Wizard", it gives you options for each category that it is configuring.  For instance, the first category is Connection Type.  If you select the "Do not change connection type" radio button, you are just ignoring that category.  Select "Do not change..." for everything except for Web Services Configuration.  That is what changes the firewall settings.

Thanks for the suggestion.  I ran IECW and reset the firewall.  No change in the problem.

Other clues to the mystery.  As I stated, I am able to bring up companyweb in Firefox using Admin credentials but I have found that I can not open OWA or Remote via Firefox. I get a 403 Forbidden error in Firefox and the 401 error in IE when I try and open either in the SBS box. (I can open both on all other clients).  I also have a security event id 537 that coincides with the failed IE authentications. Feels more like an IIS or ISA or both issue.


Thanks

Maybe it's your IE's proxy settings on the server. You might try setting the server's IE proxy to bypass local addresses.

Same problem exists with IE proxy set to bypass local addresses or not.  (It was aready set to bypass).

Thanks

Maybe with no proxy settings at all???

Still no cigar.  I have another SBS box in our other office that does not have this problem.  They are virtually identical in setup with the exception of ISA 2004 (fully patched without the ISA\update)  I really think the ISA update last week hosed IIS authentications on the affected server.  There are several people on other forums that are experiencing the exact same issue.  Some of these others have contacted Microsoft and have gotten nowhere.

Thanks for your continuing efforts.
