Roaming profiles - Specified network name is no longer available

This is a problem that has made me put a gun to my head. Large roaming
profiles will not complete in a logon process to a new local machine the user
has never logged onto before. The error is:

"Windows cannot copy file \\cej-serv01\Home\tkiley\profile\My Documents\My
Pictures\webmailpics\Thumbs.db to location C:\Documents and
Settings\tkiley.002\My Documents\My Pictures\webmailpics\Thumbs.db. Possible
causes of this error include network problems or insufficient security
rights. If this problem persists, contact your network administrator.

DETAIL - The specified network name is no longer available."

Then the user is logged in with a temporary profile.

However, this thumbs.db file does not exist in the server location!!! And
can someone explain why it is "My Documents" in this error, yet in Windows
Explorer on the server it is "tkiley's Documents". Sometimes I get the error
when the file does exist too however. And it is almost always under the My
Documents folder.

The Administrators group owns the profile directory. The system,
administrators, and user have full control of the directory. I did a copy
rights and a propagate to all subdirectories and files in the NTFS
permissions.

Are you sure you're looking at *all* files and folders?

That would be odd - My Documents is the normal path.

Couple of notes -

Redirect My Documents to a subfolder of the user's home directory using
group policy
Keep profile sizes *tiny* if you want them to work smoothly
How big is this profile?
Permissions sound fine.

The profile sizes are large. The one particular one I am troubleshooting is
200MB. But Microsoft doesn't say anything about how small or large they can
be. What's the deal? I will try your idea....

Youch. I would try to keep profiles at 30MB and under. Ideally, a lot under.
Remember, every time the user logs in/out, they're dragging those files up &
down your network. I don't know that there's an official size limit dictated
by MS - just that large profiles tend to cause tons of problems. You're
seeing some!

As suggested, redirect My Docs to a subfolder of the user's home directory
via policy. You can also redirect Desktop, but I prefer to holler at users
who store files (as opposed to shortcuts) on their desktops, and they're
scared of me. There's more you can do, but this is a good start.

I don't think it's a problem with the profiles as such but the size in
general.
I found copying large files causes similar issues (it normally is not an
issue in a switched n/w) but today we had the same problem on a newly
formatted laptop (not raming profiles) just copying a 1.6 gb file resulted
in the same error.

I believe it has to do with something along the lines of SMB timeout but I
cant find much on it (definitavely)

I'd be interested to know if you resolve this with a 200mb profile.

Yes, I seem to recall that sort of thing being caused by SMB locking. If
some other process gets the file and locks it, the session times out and
gives that "network name no longer available" message.
