The instructions I posted above worked PRIOR to installing SP1. After I installed
SP1 and went through the whole upgrading critical updates deal, I found I had one
of the same copy issues--I couldn't copy reliably to a Win98 machine large file data
FROM the XP machine.
I did some work, modified some more registry entries, researched the Microsoft Knowledgebase,
and found more than one article [ like
http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b810173 ] that seem to
indicate there is a problem (probably a "feature") that slows down/breaks file connections
over SPX. Also, it seems that performance is reduced after SP1 on some networking
conditions, and more than one article stated something to the effect that a hotfix
was available if you generated a support call ($ for Microsoft).
My solution: Go back to TCP/IP, and try it again. Suprisingly, I got it to work,
with the following additional configuration: (Who knows if this would have worked
the first time...)
In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Add or modify a DWORD "EnableOpLockForceClose" with value 0. This I was able to verify
was directly responsible for it work or not -- with this value set at 1, it failed,
but with it at 0, it worked.
So, those who begin by looking for TCP/IP instructions like the IPX/SPX instructions
above should first add the value "EnableOpLockForceClose" like I've said, and then
follow the IPX/SPX instructions, steps 2-5, substituting TCP/IP for every instance
of IPX/SPX.
Summary of whole XP/98 issue:
a. XP can often read fast (may require some help), but not write fast, to 98 machines
b. Large files are harder to transfer than a bunch of smaller ones
c. XP may require modification to (it seems, at most) three areas of the registry,
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\RemoteComputer\NameSpace
d. Good speed depends on exclusively binding a protocol to "Client for Microsoft
Networks" and "File and Printer Sharing"
e. Provider order should list "Microsoft Windows Network" FIRST, for best performance
Any feedback is appreciated...
