I'm surprised there isn't more outright swearing on this list! �I spent the whole day on this, sitting down with one working machine�side-by-side the�nonworking machine, comparing every setting I could think of, digging deep into Windows' innards in search of some enemy flag.
Looking at a Wireshark dump, it turns out that after the two OIDs�we have a mechToken [ASN1_CONTEXT(2)] instead of a principal [ASN1_CONTEXT(3)].
... the "Invalid parameter" error suddenly made a lot more sense. �I checked out the list of installed software on the nonworking machine and found that Windows Live Essentials 2011 had been installed on 11/23. �11/23?!?! �Why was that date so familiar? �I logged into BackupPC's web GUI and, yes, 11/23 was the date of the last successful backup of my nonworking machine.
Solving the problem was as easy as uninstalling Windows Live Essentials 2011 and turning off Automatic Updates. �I could have tried to apply one of the patches attached to the bug report, but I prefer to keep to the repositories whenever possible.
So there you have it. �Thread solved. -Frank � 2010/12/14 Frank J. G� <frank AT crop-circle DOT net>
I've just compared the Windows build on the problematic machine versus one of the working machines (by checking registry key�HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion), and they are the same.
Arg! �What gives?! 2010/12/14 Frank J. G� <frank AT crop-circle DOT net>
Google has not been my friend on this issue. �In fact, if you search on my error code today, most of what you'll find is this thread!
Okay, here's an update:
From my BackupPC server, which uses smbclient version 3.4.7, these commands fail:
smbclient \\\\10.10.10.111\\win7home -U username -E -d 3 smbclient \\\\10.10.10.111\\win7home -U backuppc -E -d 3
From another Windows 7 machine, I can connect with these commands:
net use k: \\10.10.10.111\win7home /user:username net use k: \\10.10.10.111\win7home /user:backuppc
My Ubuntu laptop uses smbclient 3.5.4; I can't connect from there either.
I have other Windows 7 machines in the office that I can connect to, and I was able to connect to 10.10.10.111 until about 3 weeks ago, before I assigned the machine to its user, who evidently screwed something up.
I'm willing to entertain any possibility; please share your ideas! -Frank On Tue, Dec 14, 2010 at 8:54 AM, Carl Wilhelm Soderstrom <chrome AT real-time DOT com> wrote:

Have you tried putting the error into Google and seeing what results come
up?
