Can't copy large files from XP Share

Post in reply to: mzfl
I have the same problem when copying from an XP Share on a workgroup.

I can't copy from an XP share to a Vista SP1 laptop ...actually two
different laptops. The limit seems to be 20 Meg for a wireless and
around 100 Meg for a wired connection, almost as if there is a 'time
out' on the copying time. The limit is reached whether it is one file
or many files. When the limit is reached, any files below the limit
will copy correctly. After the limit is reached, the 'Retry' window
will popup. If 'Retry' is pressed, it will copy another limit's worth
of files.

The source XP system is in a windows Workgroup, XP Professional SP2
with the LinkLayer update for Vista added. I took the same laptop to work

and it worked fine on a Domain PC with an XP share folder.


The destination system is a brand new Vista Home Premium with SP1
preinstalled. The network adapters were updated with the latest
drivers.


When the firewalls and all AntiVirus are disabled, the problem still
occurs.
The windows accounts and password match on both systems.
Sharing is turned on and Everyone has read permissions.


On both Vista, file sharing on or off makes no difference
Also, password protection on or off makes no difference.
The transfer quota is set to unlimited.
Windows firewalls are turned off.
The router is a D-Link DIR -655.
When attempting a wired copy, the wireless is disabled.


XP to XP copies work fine. And from Vista to XP works fine (opposite
direction), as does Vista to Vista. It only fails from XP to Vista.


Any help would be appreciated. Cross posted to
microsoft.public.windows.vista.general.
Also as a response to mzfl on 6/21.

I have an open incident with Microsoft, but so far, they have not been able
to resolve the situation.

I highly suspect the new file copy algorithm / permission validation in the
new SP1. SP1 was supposed to correct the file copy problems, but I don't
think it did for some OS installs.


Thanks in advance

For troubleshooting, try to disable auto tuning. If that doesn't work, test
MTU size. These links may help

How to determine the optimal MTU
In a case you may need to modify the MTU size and wonder how to
determine the optimal MTU for your system. You can use ping command to do
so, for example, ...

I had a similar problem with my XP (Home) machine. I usually streamed music
and media off it, and after a few hours it would just stop
responding...sometimes it'd come back, sometimes it'd throw me "connection
limit reached" errors, sometimes it'd just give me an unknown error..other
times the XP machine would just reboot. After switching to wired on the xp
machine, the problem got better, but not much..and noticed when copying
large files it would stop just like if i was streaming media.

http://support.microsoft.com/kb/106167 <- I followed the advice here and
made the IRPStackSize entry in my registry 50, because the limit in XP is
50. (article says 12, which was the old NT limit)

I also tried the tcpip.sys modifiacation i found here
(http://www.lvllord.de/?url=tools) - and lastly i turned off autodisconnect
with the command "Net Config Server /autodisconnect:-1"

since then i've had no issues when sharng files between my xp machine and
the vista laptop.

Thanks J!

I tried the 106167 fix, but no change. Then I tried the net config change
on both systems, but that made no change either.
Which PC was it supposed to be on, XP or Vista?

I'll try the tcpip.sys mod tonight and let you know. Microsoft themselves
haven't tried either of those two options.

Is the tcpip.sys mod on the XP (source) or Vista (destination)?

Thanks,
