I discovered the fix to my problem on an XP networked system: uninstall
Hotfix KBB88520. If you are experiencing a networked XP Pro & Home system
where all was well with the network and you could see all files, etc. on the
XP Pro system until you installed XP SP2 & the 13 "critical" hotfixes, then
you MUST uninstall KBB885250. NOTHING ELSE WORKS AT ALL - period. I am an
expert computer user with 15 years networking experience and no matter what
you try there is no other solution. Thx Mr. Gates.

Wow, I'm sorry that the hotfix gave you so much trouble. I've seen
another report saying that it caused problems between Windows
networking and SAMBA. However, that report said that XP SP2 clients
seem unaffected and that the problem is only on XP SP1 clients.

KB885250 is installed on my four XP computers as of 2/11/2005, and
networking is working fine on all of them. I wonder why we got such
different results from it.

The hotfix patches a Server Message Block (SMB) vulnerability. By
default, Windows XP use NetBIOS over TCP/IP for file and printer
sharing Have you disabled NetBIOS over TCP/IP, which would make the
system use SMB instead?

The "Vulnerability Details" section of this web page gives some ways
to get protection from the vulnerability without using the hotfix:

Microsoft Security Bulletin MS05-011
Vulnerability in Server Message Block Could Allow Remote Code
Execution (885250)

Absolute hogwash from either a troll or someone who is completely
uninformed, whose experience could be a repetition 15 years of introductory
networking.
The hotfix addresses an issue with Windows and SAMBA - in case you
didn't know, normally SAMBA runs on an *ix flavored machine to enable file
sharing (versus using an NFS mount point) similar to Windows File Sharing.
So with all your technical knowledge, explain to me how a fix dealing
with SAMBA has broken your puny XP Pro/XP Home network, where SAMBA is not
involved? Or are you file sharing with GNU's latest version of SAMBA on your
XP Pro/XP Home systems? If so then there was a Patch release by the Open
Source groups to fix the "same" issue.

i work with many companies networks running peer XP pro, and have 24 years
experience.
out of 11 companies 7 lost their shared subfolders after this hotfix. these
are systems which literally havent crashed or had any errors for the
months/years XP PRO has been on them.
when uninstalling this hotfix, shared subfolders are back. period. it works.

i have the problem though on 3 systems where under ADDREMOVE i do not see an
entry for this hotfix, and i am wondering if theres another way to uninstall
this hotfix, or if someone can tell me manually which files to place back
from a pre-hotfix machine, so i can finish the 3 off.

thanks
gg

If these are peer-to-peer workgroups and the aforementioned hotfix
caused a loss of shares on certain PC's, then the PC's and/or workgroup
and/or share is/was NOT properly configured. Meaning you've installed and
are using protocol(s) that have no business being there.
That's the number one issue with people who "install" all networking
protocols on everything, but you open your self up to so many more issues,
not to mention more of a chance to be hit with a backdoor Trojan or DOS
attack. This is one case where throwing in the "kitchen sink" is not
helpful. The saying "more" is "better", doesn't apply here either - it is
actually being "lean" is "mean".
Oh well, its your job, your networks, your weekends lost, not mine.

This is absolutely *NOT* true. kb885250 causes an INTERMITTENT loss of
access to arbitrary shared folders on properly configured windows xp and
2000 machines.
Samba is NOT the problem--I don't use SAMBA at all--the patch breaks all
Windows SMB access! And xp sp2 clients *ARE* definitely affected. I
suspect people who have not yet encountered a problem will encounter it at
some point--not all or even most folders are affected, but it's arbitrary,
unpredictable denial of access to a few folders.

If you've encountered the kb885250 breaking of windows xp networks, please
submit a complaint, so that the problem will be corrected more quickly.

please note this post from the other thread on where to report this bug
(again, note that it is not an issue with samba or network configuration; it
is a bug in the 885250 patch that breaks windows networks):

Thanks, I'll report it to ms at those websites as a critical/severe bug:
kb885250 arbitrarily prevents access to some but not all shared folders on
properly configured windows xp sp2 and other windows networks, both
peer-to-peer and client/server.

(It may be that only people using netbios, i.e. non-dns style, names are
seeing it, but that still makes it a widespread problem. Despite what that
rep said, I assume they'll withdraw or fix kb885250 over the next few weeks
as the complaints increase and the cause is tracked down.)

Hello James,

I am experiencing the same problem in our environment also, I placed a call
to Microsoft support and they are working with me to resolve this issue, I
will let you know what the fix is when it is resolved.
