Delayed Write Failure

I am running W2K3 SP1 server standard on a small home network.  Dell SC420 server is file server, domain controller, DNS, DHCP for 3 XP Pro clients.  In the past I used NTbackup to work a simplistic rotation of a weekly full and a daily differential.  These were sent over the network so one of the XP Pro computers on a large hard drive just for this purpose.  Life was pretty good for several months and the rotation worked flawlessly until a couple of months ago.  The delayed write failures began and regardless of which XP Pro computer I used, the error hits at about 4GB of progress on the NTbackup.  I cannot say when the problems started or pin it to any patch or upgrade.   Here is what all I have tried or know:

1)  Replaced MB on W2K3 server (tired to flash the bios and it hung up)
2)  Changed patch cords, changed router/switch
3)  Direct connected a client with the server via a crossover cable
4)  Set system memory usage to "programs" instead of "system caching"
5)  Get the same error with Retrospect as I do with NTbackup
6)  Have tried different XP Pro clients
7)  Am able to transfer large files (6GB) via "copy" without problem as well as the native folder structure (15 GB)
8)  Am able to backup this same 6GB single file with NTBackup over the LAN
9)  Set all NICs to 100 Full
10)  Errors are below
11)  Note the error re: master browser and the time - could this be a clue?

Need to get back to business and could use some expert suggestions.

See http://support.microsoft.com/kb/q129202/.  You need to disable oplocks.

I had exactly the same problem, and even though I could get the delayed write failures to go away, I could not stop retrospect from hanging.  It just doesn't like huge disk backups over the network.  Good luck dude.

I went to give that a try and lo and behold - EnableOplocks per the Microsoft article is not in the Windows 2003 Server registry.  Apparently a legacy of NT 4.0.

Went to this registry key and the "OplocksDisabled" entry is not there.  Should I add it or is its absence an indicator of something else?

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters\
OplocksDisabled REG_DWORD 0 or 1
Default: 0 (not disabled)
