Long delay in copying small files on shared drive

Client PC: WinXP SP3
Server: Windows 2003 Server Enterprise Ed. SP2

Problem: Often, but not always, when using Windows Explorer to copy a small
group (about 3) of small (under 1K) text files from one folder to another on
the same mapped drive, it will take about 30 seconds to a minute before the
overwrite confirm dialog box appears. After confirming the copy, the file
progress bar appears for another period much longer than should be necessary
to copy files of this size. When copying the same files using the Copy
command, there is no noticeable delay.

The following packet trace shows a three instances of a long delay. Each
seems to involve a TCP request that looks like:

TCP wfremotertm > microsoft-ds [ACK] Seq=7911 Ack=10372 Win=65089 [TCP
CHECKSUM INCORRECT] Len=0

There are no retransmissions, so I think the incorrect checksum is due to
hardware offload, correct?

The delays occur around packets 115, 264, 310, 362, & 434

Can anyone tell me what's causing this?

I have been having similar problems recently.
Disabling the NIC tcp/offload got rid of the related errors, but not the
slow file transfer.

I'm focusing on the SMB protocol and NT-Trans errors.

I'll post more once I've resolved my problem.

Windows XP has an explorer windows browsing a network drive and often doesn't react "Not responding" ,

wireshark logging shows me it takes 5s that there is no activity on the network between the server & my host XP machine.

Offload disabling for the NIC, didn't work.

I put the 1Gb NIC fix on 100Mb/Full duplex, didn't help.


any other suggestions?

Long delay in copying small files on shared drive
Client PC: WinXP SP3
Server: Windows 2003 Server Enterprise Ed. SP2

Problem: Often, but not always, when using Windows Explorer to copy a small
group (about 3) of small (under 1K) text files from one folder to another on
the same mapped drive, it will take about 30 seconds to a minute before the
overwrite confirm dialog box appears. After confirming the copy, the file
progress bar appears for another period much longer than should be necessary
to copy files of this size. When copying the same files using the Copy
command, there is no noticeable delay.

The following packet trace shows a three instances of a long delay. Each
seems to involve a TCP request that looks like:

TCP wfremotertm > microsoft-ds [ACK] Seq=7911 Ack=10372 Win=65089 [TCP
CHECKSUM INCORRECT] Len=0

There are no retransmissions, so I think the incorrect checksum is due to
hardware offload, correct?

The delays occur around packets 115, 264, 310, 362, & 434

Can anyone tell me what's causing this?
