This would most likely just be a conflict with the fact that Microsoft Windows
NT Services for Macintosh (SFM) does not support the MacOS native concurrent
users feature. AppleShare servers can allow more than one user launch
applications and and locked documents. However, just as you are
expierencing, the MacOS will inform a user is a file is open by another for
editing and will refuse access.

What it sounds like is maybe BBEdit is not opening/closing file ids and locks
correctly on the Windows NT Server. Try another application to see if the
same problem is exhibited. In BBEdit look to see if you are using the Project
management features and make sure that files are not locked or checked-out.
You would need to check them back in before you would be able to view them on
the IIS server -> browser.

Sounds like a bug in the Windows NT SFM functions. You might want to report
this to Microsoft and see what they have to say.

This is a known bug in Windows NT SFM. It is documented in the Microsoft
TechNet under article #Q158396. The article say they will have a fix later.
Not sure if one exists. Looking through the July 1998 TechNet shows not
update to the article.

TITLE: Explorer Hangs When Creating a New Folder on a MAC Volume.

SYMPTOMS
========
Windows NT Explorer may stop responding (hang) for 10-20 second when you type
a new folder name on a local or remote Macintosh-accessible (SFM UAM) volume
or folder. After the hang, the new folder name reverts to "New Folder" until
you refresh the window. At this time the folder name becomes the incomplete
name entered before your computer stopped responding. You can now rename the
incomplete folder name to a new folder name without experiencing the same
behavior.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We
are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.

Additional query words: 4.00 prodnt macfile non-repsonsive lock locks
freezes hangs.

Hope this helps! :) ..Greg
